WIP: PDB-407 Fedora 20 Acceptance Testing

DO NOT MERGE: contains git specific paths to a beaker fix, just running it through CI for now until that fix is merged into beaker.

This adds a fedora 20 image to the acceptance testing image list, and modifies
any tests that need modification for these tests to pass.
