By default, integration tests destroy the test instances after each
test run. To aid debug and development of integration tests, support a
--preserve-instance argument which will leave the modified test instance
in a stopped state for further debug.

The NoCloud KVM platform includes:
* Downloads daily Ubuntu images using streams and store in
/srv/images
* Image customization, if required, is done using
mount-image-callback otherwise image is untouched
* Launches KVM via the xkvm script, a wrapper around
qemu-system, and sets custom port for SSH
* Generation and inject an SSH (RSA 4096) key pair to use for
communication with the guest to collect test artifacts
* Add method to produce safe shell strings by base64 encoding
the command
Additional Changes:
* Set default backend to use LXD
* Verify not running script as root in order to prevent images
from becoming owned by root
* Removed extra quotes around that were added when collecting
the cloud-init version from the image
* Added info about each release as previously the lxd backend
was able to query that information from pylxd image info,
however, other backends will not be able to obtain the same
information as easily

Massive update to clean up and greatly enhance the integration testing
framework developed by Wesley Wiedenmeier.
- Updated tox environment to run integration test 'citest' to utilize
pylxd 2.2.3
- Add support for distro feature flags
- add framework for feature flags to release config with feature groups
and overrides allowed in any release conf override level
- add support for feature flags in platform and config handling
- during collect, skip testcases that require features not supported by
the image with a warning message
- Enable additional distros (i.e. centos, debian)
- Add 'bddeb' command to build a deb from the current working tree
cleanly in a container, so deps do not have to be installed on host
- Adds a command line option '--preserve-data' that ensures that
collected data will be left after tests run. This also allows the
directory to store collected data in during the run command to be
specified using '--data-dir'.
- Updated Read the Docs testing page and doc strings for pep 257
compliance

This will change all instances of LOG.warn to LOG.warning as warn
is now a deprecated method. It will also make sure any logging
uses lazy logging by passing string format arguments as function
parameters.

The adds in end-to-end testing of cloud-init. The framework utilizes
LXD and cloud images as a backend to test user-data passed in.
Arbitrary data is then captured from predefined commands specified
by the user. After collection, data verification is completed by
running a series of Python unit tests against the collected data.
Currently only the Ubuntu Trusty, Xenial, Yakkety, and Zesty
releases are supported. Test cases for 50% of the modules is
complete and available.
Additionally a Read the Docs file was created to guide test
writing and execution.
