Custom style rules for ansible-lint

[Jesse Pretorius]

We, as a community, have certain style preferences which we currently enforce by review - but which could be more easily enforced through custom lint plugins for ansible-lint.

It'd be great if we could put together a custom plugin to verify through ansible-lint that http://docs.openstack.org/developer/openstack-ansible/developer-docs/contribute.html#ansible-style-guide are met.

Once we have an example to work from we can then extend both the style guide and the custom checks to do more of the things we care about enforcing for various reasons.
