(#1123)
Allow #cloud-config and cloud-init query to use underscore-delimited
"jinja-safe" key aliases for any instance-data.json keys
containing jinja operator characters.
This provides a means to use Jinja's dot-notation instead of square brackets
and quoting to reference "unsafe" obtain attribute names.
Support for these aliased keys is available to both #cloud-config user-data and
`cloud-init query`.
For example #cloud-config alias access can look like:
{{ ds.config.user_network_config }}
- instead of -
{{ ds.config["user.network-config"] }}

This is more consistent with other github repositories, and will prompt
a first-time contributor to read the contributing guidelines before
submitting the pull request.
Additionally, added a summary section to the top, updated some outdated
language, and removed some outdated typing guidance.

Add DataSourceLXD which knows how to talk to the dev-lxd socket to
obtain all instance metadata API:
https://linuxcontainers.org/lxd/docs/master/dev-lxd.
This first branch is to deliver feature parity with the existing
NoCloud datasource which is currently used to intialize LXC instances
on first boot.
Introduce a SocketConnectionPool and LXDSocketAdapter to support
performing HTTP GETs on the following routes which are surfaced by the
LXD host to all containers:
http://unix.socket/1.0/meta-data
http://unix.socket/1.0/config/user.user-data
http://unix.socket/1.0/config/user.network-config
http://unix.socket/1.0/config/user.vendor-data
These 4 routes minimally replace the static content provided in the
following nocloud-net seed files:
/var/lib/cloud/nocloud-net/{meta-data,vendor-data,user-data,network-config}
The intent of this commit is to set a foundation for LXD socket
communication that will allow us to build network hot-plug features
by eventually consuming LXD's websocket upgrade route 1.0/events to
react to network, meta-data and user-data config changes over time.
In the event that no custom network-config is provided, default to the
same network-config definition provided by LXD to the NoCloud
network-config seed file.
Supplemental features above NoCloud datasource:
surface all custom instance data config keys via cloud-init query ds
which aids in discoverability of features/tags/labels as well as
conditional #cloud-config jinja templates operations based on custom
config options.
TBD: better cloud-init query support for dot-delimited keys

Also, add the "signed by" option to source definitions. This enables
users to limit the scope of trust for individual keys.

This commit removes automatically installing udev rules for hotplug
and adds a module to install them instead.
Automatically including the udev rules and checking if hotplug was
enabled consumed too many resources in certain circumstances. Moving the
rules to a module ensures we don't spend extra extra cycles on hotplug
if hotplug functionality isn't desired.

There is no reason for the ISO missing this functionality.

In #919 (81299de), we refactored some of the code used to bring up
networks across distros. Previously, the call to bring up network
interfaces during 'init' stage unintentionally resulted in a no-op
such that network interfaces were NEVER brought up by cloud-init, even
if new network interfaces were found after crawling the metadata.
The code was altered to bring up these discovered network interfaces.
On ubuntu, this results in a 'netplan apply' call during 'init' stage
for any ubuntu-based distro on a datasource that has a NETWORK
dependency. On GCE, this additional 'netplan apply' conflicts with the
google-guest-agent service, resulting in an instance that can no
be connected to.
This commit adds a 'disable_network_activation' option that can be
enabled in /etc/cloud.cfg to disable the activation of network
interfaces in 'init' stage.

OpenNebula 6.1.80 (current dev. version) is introducing new IPv6 gateway
contextualization variable ETHx_IP6_GATEWAY, which mimics existing
variable ETHx_GATEWAY6. The ETHx_GATEWAY6 used until now will
be depracated in future relase (ET spring 2022).
See:
- new variable - https://github.com/OpenNebula/one/commit/e4d2cc11b9f3c6d01b53774b831f48d9d089c1cc
- deprecation tracking issue - https://github.com/OpenNebula/one/issues/5536
Also, added support for SET_HOSTNAME context variable, which is
currently widely used variable to configure guest VM hostname. See
https://docs.opennebula.io/6.0/management_and_operations/references/template.html#context-section

- update the puppet module to support AIO installations by setting
`install_type` to `aio`
- make the install collection configurable through the `collection`
parameter; by default the rolling `puppet` collection will be used,
which installs the latest version)
- when `install_type` is `aio`, puppetlabs repos will be purged after
installation; set `cleanup` to `False` to prevent this
- AIO installations are performed by downloading and executing a shell
script; the URL for this script can be overridden using the
`aio_install_url` parameter
- make it possible to run puppet agent after installation/configuration
via the `exec` key
- by default, puppet agent will run with the `--test` argument; this can
be overridden via the `exec_args` key

This patch finally introduces the Cloud-Init Datasource for VMware
GuestInfo as a part of cloud-init proper. This datasource has existed
since 2018, and rapidly became the de facto datasource for developers
working with Packer, Terraform, for projects like kube-image-builder,
and the de jure datasource for Photon OS.
The major change to the datasource from its previous incarnation is
the name. Now named DatasourceVMware, this new version of the
datasource will allow multiple transport types in addition to
GuestInfo keys.
This datasource includes several unique features developed to address
real-world situations:
* Support for reading any key (metadata, userdata, vendordata) both
from the guestinfo table when running on a VM in vSphere as well as
from an environment variable when running inside of a container,
useful for rapid dev/test.
* Allows booting with DHCP while still providing full participation
in Cloud-Init instance data and Jinja queries. The netifaces library
provides the ability to inspect the network after it is online,
and the runtime network configuration is then merged into the
existing metadata and persisted to disk.
* Advertises the local_ipv4 and local_ipv6 addresses via guestinfo
as well. This is useful as Guest Tools is not always able to
identify what would be considered the local address.
The primary author and current steward of this datasource spoke at
Cloud-Init Con 2020 where there was interest in contributing this datasource
to the Cloud-Init codebase.
The datasource currently lives in its own GitHub repository at
https://github.com/vmware/cloud-init-vmware-guestinfo. Once the datasource
is merged into Cloud-Init, the old repository will be deprecated.

Currently cloud-init generates fallback network config on various
scenarios.
For example:
1. When no DS found
2. There is no 'network' info given in DS metadata.
3. If a DS gives a network config once and upon reboot if DS doesn't
give any network info, previously set network data will be
overridden.
A newly introduced key in cloud.cfg.tmpl can be used to control this
behavior on PhotonOS.
Also, if OS comes with a set of default network files(configs), like in
PhotonOS, cloud-init should not overwrite them by default.
This change also includes some nitpicking changes of reorganizing few
config variables.

Adds a udev script which will invoke a hotplug hook script on all net
add events. The script will write some udev arguments to a systemd FIFO
socket (to ensure we have only instance of cloud-init running at a
time), which is then read by a new service that calls a new 'cloud-init
devel hotplug-hook' command to handle the new event.
This hotplug-hook command will:
- Fetch the pickled datsource
- Verify that the hotplug event is supported/enabled
- Update the metadata for the datasource
- Ensure the hotplugged device exists within the datasource
- Apply the config change on the datasource metadata
- Bring up the new interface (or apply global network configuration)
- Save the updated metadata back to the pickle cache
Also scattered in some unrelated typing where helpful

v1 network config currently has no concept of interface-specific DNS,
which is required for certain renderers. To fix this, added an
optional 'interface' key on the v1 nameserver definition. If
specified, it makes the DNS settings specific to the interface.
Otherwise, it will be defined as global DNS as it always has.
Additionally, DNS for v2 wasn't being recognized correctly. For DNS
defined on a particular interface, these settings now also go into the
global DNS settings as they were intended.

- Mostly based on FreeBSD, the main exception is that
`find_devs_with_on_freebsd` does not work.
- Since we cannot get the CDROM or the partition labels,
`find_devs_with_on_dragonflybsd()` has a more naive approach and
returns all the block devices.

instance-data.json redacts sensitive data for non-root users. Since user

Presently, mirror keys cannot be associated with primary/security
mirrors. Unfortunately, this prevents use of Landscape-managed
package mirrors as the mirror key for the Landscape-hosted repository
cannot be provided.
This patch allows the same key-related fields usable on "sources"
entries to be used on the "primary" and "security" entries as well.

Control is currently limited to boot events, though this should
allow us to more easily incorporate HOTPLUG support. Disabling
'instance-first-boot' is not supported as we apply networking config
too early in boot to have processed userdata (along with the fact
that this would be a pretty big foot-gun).
The concept of update events on datasource has been split into
supported update events and default update events. Defaults will be
used if there is no user-defined update events, but user-defined
events won't be supplied if they aren't supported.
When applying the networking config, we now check to see if the event
is supported by the datasource as well as if it is enabled.
Configuration looks like:

when: ['boot']

This reverts commit 74fa008bfcd3263eb691cc0b3f7a055b17569f8b.
During pre-release testing, we discovered two issues with this commit.
Firstly, there's a typo in the udevadm command that causes a TypeError
for _all_ growpart executions. Secondly, the LVM resizing does not
appear to successfully resize everything up to the LV, though some
things do get resized.
We certainly want this change, so we'll be happy to review and land it
alongside an integration test which confirms that it is working as
expected.

This patch adds support to resize a single partition of a VM if it's using an
LVM underneath. The patch detects if it's LVM if the given block device
is a device mapper by its name (e.g. `/dev/dm-1`) and if it has slave
devices under it on sysfs. After that syspath is updated to the real
block device and growpart will be called to resize it (and automatically
its Physical Volume).
The Volume Group will be updated automatically and a final call to
extend the rootfs to the remaining space available will be made.
Using the same growpart configuration, the user can specify only one
device to be resized when using LVM and growpart, otherwise cloud-init
won't know which one should be resized and will fail.

If cloud-init is enabled on VMware platform, cloud-init will wait until
its configuration file is ready and currently the max wait is 90
seconds by default. With our test, this configuration file should be
ready within 1 second, so change it to 15 seconds for better
performance. Also update the documentation about how to change the
default value in cloud-init configuration file.
