This is not yet called, but will be called in a subsequent Ec2-related branch to manually initialize a network interface with the responses using dhcp discovery without any dhcp-script side-effects. The functionality has been tested on Ec2 ubuntu and CentOS vms to ensure that network interface initialization works in both OS-types.
Since there was poor unit test coverage for the cloudinit.net.__init__ module, this branch adds a bunch of coverage to the functions in cloudinit.net.__init. We can also now have unit tests local to the cloudinit modules. The benefits of having unittests under cloudinit module:
- Proximity of unittest to cloudinit module makes it easier for ongoing devs to know where to augment unit tests. The tests.unittest directory is organizated such that it
- Allows for 1 to 1 name mapping module -> tests/test_module.py
- Improved test and module isolation, if we find unit tests have to import from a number of modules besides the module under test, it will better prompt resturcturing of the module.
This also branch touches:
- tox.ini to run unit tests found in cloudinit as well as include all test-requirements for pylint since we now have unit tests living within cloudinit package
- setup.py to exclude any test modules under cloudinit when packaging

cloud-init.service may write filesystems (fs_setup) or re-partition
(disk_setup) disks.
If systemd-fsck is running on a device while that is occuring
then the partitioning or mkfs might fail due to the device being busy.
Alternatively, the fsck might fail and cause subsequent mount to fail.

Under el7, cloud-init systemd files need some unit tweaks to ensure
they run at the right time. Pull in current el7 downstream systemd unit
changes.

Cloud-init's template renderer does not require the use of cheetah
(which is python2 only) so do not put it in the list of package
requirements.

Here we move the config/cloud.cfg to be rendered as a template.
That allows us to maintain deltas between distros in one place.
Currently we use 'variant' variable to make decisions.
A tools/render-cloudcfg is provided to render the file.
There were changes to setup.py, MANIFEST.in to allow us to put all
files into a virtual env installation and to render the cloud-config
file in 'install' or 'bdist' targets.
We have also included some config changes that were found in the
redhat distro spec.
* include some config changes from the redhat distro spec.
The rendered cloud.cfg has some differences.
Ubuntu: white space and comment changes only.
Freebsd:
- whitespace changes and comment changes
- datasource_list definition moved to be closer to 'datasource'.
- enable modules: migrator, write_files
- move package-update-upgrade-install to final.
The initial work was done by Josh Harlow.

This patch targets to make FreeBSD 10.3 or 11 work on Azure. The
modifications abide by the rule of:
* making as less modification as possible
* delegate to the distro or datasource where possible.
The main modifications are:
1. network configuration improvements, and movement into distro path.
2. Fix setting of password.
Password setting through "pw" can only work through pipe.
3. Add 'root:wheel' to syslog_fix_perms field.
4. Support resizing default file system (ufs)
5. copy cloud.cfg for freebsd to /etc/cloud/cloud.cfg rather than
/usr/local/etc/cloud/cloud.cfg.
6. Azure specific changes:
a. When reading the azure endpoint, search in a different path
and read a different option name (option-245 vs. unknown-245).
so, the lease file path should be generated according to platform.
b. adjust the handling of ephemeral mounts for ufs filesystem and
for finding the ephemeral device.
c. fix mounting of cdrom

Add a basic snapcraft.yaml file to allow the execution of cloud-init as
a snap. This will always pull down the latest source from master for
the snap. setup.py will now also set the default init system to be
systemd when no other is passed to it.

ds-identify is run here from the generator. If ds-identify does
not see any datasources, it can completely disable cloud-init.
The big value in this is that if there is no datasource, no python
will ever be loaded, and cloud-init will be disabled.o
The default policy being added here is:
search,found=all,maybe=all,notfound=disabled
That means:
- enable (in 'datasource_list') all sources that are found.
- if none are found, enable all 'maybe'.
- if no maybe are found, then disable cloud-init.
On platforms without DMI (everything except for aarch64 and x86),
the default 'notfound' setting is 'enabled'. This is because many of
the detection mechanisms rely on dmi data, which is present only on
x86 and aarch64.

This has been a recurring ask and we had initially just made the change to
the cloud-init 2.0 codebase. As the current thinking is we'll just
continue to enhance the current codebase, its desirable to relicense to
match what we'd intended as part of the 2.0 plan here.
- put a brief description of license in LICENSE file
- put full license versions in LICENSE-GPLv3 and LICENSE-Apache2.0
- simplify the per-file header to reference LICENSE
- tox: ignore H102 (Apache License Header check)
Add license header to files that ship.
Reformat headers, make sure everything has vi: at end of file.
Non-shipping files do not need the copyright header,
but at the moment tests/ have it.

Adds an install option for for OpenRC init scripts.
I've also restricted installing tests more correctly.
Also, don't hardcode the path to ip (/bin/ip on gentoo).

It is more efficient and cross-distribution safe to use the hooks function
from dhclient to obtain the Azure endpoint server (DHCP option 245).
This is done by providing shell scritps that are called by the hooks
infrastructure of both dhclient and NetworkManager. The hooks then
invoke 'cloud-init dhclient-hook' that maintains json data
with the dhclient options in
/run/cloud-init/dhclient.hooks/<interface>.json .
The azure helper then pulls the value from
/run/cloud-init/dhclient.hooks/<interface>.json file(s). If that file does
not exist or the value is not present, it will then fall back to the
original method of scraping the dhcp client lease file.

Modification of the tarball became problematic, as it meant that
any tool extracting source would find the orig source tarball different.
I found this unusable when trying to use 'gbp buildpackage'.
Other changes here are to better support using python3 or python2
for the build. Makefile will try to call the right python version
and can be told which python to use.
read-version: by adding 'tiny_p' and avoiding the import of
cloudinit.util, we need less dependencies to run this.

This allows for the test_cli test to be more sane.

This didn't really work. See bug for more info.

Note, still broken as cloud-init local is not going to ever touch the
CI_NET_READY file (/run/cloud-init/network-config-ready).
So as this is , it will actually just block for 60 seconds and go on.

2. Cheetah is not compatible with Python 3.

* Use universal_newlines in setup.py so it will work properly in Python 3.
* Fix a pyflakes complaint in setup.py
* Add a simple MANIFEST.in

--ignore was being called with ',E121,E...' rather than
'E121,E...'.
that resulted in odd behavior, missing the pep8 errors that are fixed
here.

To make it so that cloud-init is installable in a virtualenv
where it can be tested in an isolated scenario we need to avoid
using and including datafiles (which won't be written into the
virtualenv) and also avoid using our initsys helper class which
also adds on its own files when we are being ran from a virtualenv.

a.) appease pylint on raring, as it doesn't like subprocess
pylint: 0.26.0-1ubuntu1
This is mentioned in comments at http://www.logilab.org/ticket/46273
b.) tests/unittests/test_util.py:
the mountinfo lines are longer than 80 chars.
Just disable long lines complaints for this file.
