[Change Request] New bodhi release

[Luke Macken]

Hey all,

I'd like to push out a new bodhi release this week.

    Policy Changes
    - Support the new pre-beta policy
        - critpath updates only requires 1 proventester karma
        - non-critpath updates can be pushed to stable after 3 days in testing

    Changes for AutoQA
    - Adds the appropriate pending tag upon reacing stablekarma
    - Remove the pending tags when revoking a request

    Testing improvements
    - Query the wiki for test cases upon new update creation and list them in the update

These changes do not require any database schema changes, and the bodhi-server
can easily be rolled back if things break.
