load_azure_ds_dir() always returns a tuple. Instead of saving this
tuple as ret, expand it immediately as md, userdata_raw, cfg, files.
This allows for more fine-grained passing of data before getting
expanded later.
- Update _should_reprovision methods to use cfg instead of tuple.
- Update _should_reprovision methods to remove the ovf_md guard.
This should be a safe refactor as the OVF is not required, and the
config is initialized to an empty dict. In practice, a mount failure
would have initialized ret anyways if the OVF was not found. If a
mount failure wasn't seen and ret was None, this guard could be
causing other failures by ignoring the PPS state that should be
available from IMDS metadata.

The if-statement set ovf_is_accessible to True if the OVF is read
from /dev/sr0, but not from other data sources. It defaults to
True, but may get flipped to False while processing an invalid
source, and never get set back to True when reading from the data
directory.
Instead, default ovf_is_accessible to False, and only set it to
True once we've read an OVF successfully (and end the search).
This fixes an error when OVF is read from data_dir and IMDS
data is unavailable (failing with "No OVF or IMDS available").

- Update EphemeralDHCPv4WithReporting to subclass EphemeralDHCPv4 for
consistency (non-functional change).
- Replace all usage of EphemeralDHCPv4 with EphemeralDHCPv4WithReporting.
- Converging to one DHCP class exposed an issue with ExitStack patches
being mixed with decorators. Specifically, it appeared that tests
that did not enable azure.EphemeralDHCPv4WithReporting mocks had it
applied anyways from previous tests.
Presumably ExitStack was overwriting the actual value with the
mock provided by the decorator? For now, remove some mock patches
that trigger failures, but future work should move towards a
consistent approach to prevent undetected effects.

In 2c52e6e88b19f5db8d55eb7280ee27703e05d75f, the order of
reading network config was changed for Oracle due to initramfs
needing to take lower precedence than the datasource. However,
this also bumped system_cfg to a lower precedence than ds, which
means that any network configuration specified in /etc/cloud will not
be applied. system_cfg should instead be moved above ds so network
configuration in /etc/cloud takes precedence.

Includes:
- Update tox.ini and .travis.yml accordingly
- Cleanup tox.ini with new tox syntax and cloud-init dependencies
- Update documentation accordingly
- Replace/remove xenial references where additional testing isn't required
- Remove xenial checks in integration tests
- Replace yield_fixture with fixture in pytest tests
Sections of code commented with lines like "Remove when Xenial is no
longer supported" still exist as they're require additional testing.

If get_imds_data_with_api_fallback() falls back to the minimum required
API version, it is effectively pinned to the old API version forever.
Remove the failed_desired_api_version property to prevent persistence of
the flag between calls and/or reboots.
The continued presence of this flag in obj.pkl should be harmless.

and CI.

Thanks to [1], the hostname is set prior to network bring-up.
The Azure data source has been bouncing the hostname during
setup(), occurring after the hostname has already been
properly configured.
Note that this doesn't prevent leaking the image's hostname
during Azure's _get_data() when it brings up ephemeral DHCP.
However, as are not guaranteed to have the hostname metadata
available from a truly "local" source, this behavior is to
be expected unless we disable `send host-name` from dhclient
config.

Add a test helper to get top level directory
Many tests need to get the location of files & dirs within the cloud-init
project directory.
Tests implement this in various different ways, and often those ways
depend on the current working directory of the pytest invocation.
Create helper functions (and tests) that gets the path of the top
directory or any sub directory under the top directory. This function
does not depend on the environment.

This attempts to standardize unit test file location under test/unittests/
such that any source file located at cloudinit/path/to/file.py may have a
corresponding unit test file at test/unittests/path/to/test_file.py.
Noteworthy Comments:
====================
Four different duplicate test files existed:
test_{gpg,util,cc_mounts,cc_resolv_conf}.py
Each of these duplicate file pairs has been merged together. This is a
break in git history for these files.
The test suite appears to have a dependency on test order. Changing test
order causes some tests to fail. This should be rectified, but for now
some tests have been modified in
tests/unittests/config/test_set_passwords.py.
A helper class name starts with "Test" which causes pytest to try
executing it as a test case, which then throws warnings "due to Class
having __init__()". Silence by changing the name of the class.
# helpers.py is imported in many test files, import paths change
cloudinit/tests/helpers.py -> tests/unittests/helpers.py
# Move directories:
cloudinit/distros/tests -> tests/unittests/distros
cloudinit/cmd/devel/tests -> tests/unittests/cmd/devel
cloudinit/cmd/tests -> tests/unittests/cmd/
cloudinit/sources/helpers/tests -> tests/unittests/sources/helpers
cloudinit/sources/tests -> tests/unittests/sources
cloudinit/net/tests -> tests/unittests/net
cloudinit/config/tests -> tests/unittests/config
cloudinit/analyze/tests/ -> tests/unittests/analyze/
# Standardize tests already in tests/unittests/
test_datasource -> sources
test_distros -> distros
test_vmware -> sources/vmware
test_handler -> config # this contains cloudconfig module tests
