OpenStack in general uses git tags to drive versioning of artifacts.
This is important because of our code review driven workflow, since
patches don't necessarily land in a predictable sequence, so flows
requiring a version number in a file to be updated at a specific
time are problematic.
By having pbr generate the correct version number then putting that
into the galaxy.yml file, we can match the behavior without too much
undue burden.
Also ignore build_artifact directory.

In module_utils we have a bunch of factory functions that we expect
people to use in a certain combination to build a module, then we
pass around a reference to the SDK and to the connection we created.
That's largely just due to how this stuff grew organically.
Instead, create a base class to be used in the modules. For now it
allows us to clean things up a bit. But as a follow on - it should
maybe help us put in things like richer logging collection which
would otherwise need to be done with helper methods and whatnot.
