Re: [charms] Zaza bundle tests

I think I remember that a conscious decision was made to avoid using symlinks for the bundles due to the hell that openstack-mojo-specs descended into?  Liam may want to wade in on this?

Broadly, this is one of the reasons I proposed submitting a review of a single charm to be a practical example of what this would look like, and how complex it would be. It should also help us, as a project, identify if the repetition is enough that symlinks, or refactoring the library, would be worthwhile.
