This allows you to extend lists in yaml config. This is useful, for
example, in prometheus.yml, where it would be nice to be able to
extend the scrape_configs to include exporters that aren't packaged
with kolla-ansible. This would provide a mechanism to do so.

This mimics behavior of core 'template' module to allow relative
includes from the same dir as merged template, base dir of
playbook/role (usually role for us) and its 'templates' subdir.

Additionally old unused code was removed.

There is inconsistent use of either `/usr/bin/python` or
`/usr/bin/env python`. This makes for unexpected results when a
user might be using a virtualenv.

It is not safe to call yaml.load with any data received from

In links: http://pythonhosted.org/six/, we know 'cStringIO' is
a module of python 2.x, but in python3.x module 'io' has the
same function as 'cStringIO' in python2.x. So here we use
six.stringIO instead.

TrivialFix.

By ignoring the appropriate tests that pep8 does we can properly run
*most* of the pep8 tests on all of our modules allowing for a more
consistent coding style.

Convert config creation from a playbook to an action_plugin. This
reduces the complexity and confusion while retaining the same augment
structure and flexibility.

This allows us to remove the 0-byte files as requirements. They will
still be used if they are present (this means we require additional
documentation around them).
