Bug Description

Conceptually, it makes more sense to service the admin API with its own driver, rather than sharing with the queues app. Two different apps, different backend DBs, different auth etc.


    class PublicDriver(...):
        def _queue_controller(self): ...
        def _message_controller(self): ...
        def _claim_controller(self): ...

    class AdminDriver(...):
        def shards_controller(self): ...
        def catalogue_controller(self): ...

DataDriver and ControlDriver ended up making a lot more sense. Admin/Public is all about the transport layer. The storage layer only cares about controls and data.

    feat: add catalogue storage driver for queues

    The upcoming sharding feature requires a catalogue storage driver very
    similar to that used by the proxy. This patch ports the proxy
    catalogue storage driver to the queues storage space and updates the
    semantics accordingly. Specifically, the queues catalogue maintains a
    mapping from project/queue to shard identifier.

    Unit tests and helpers have been updated accordingly. The sqlite
    portion of this is still to be done, and is reserved for a future

    The faulty storage drivers has been given the appropriate
    catalogue_controller impls.

    Furthermore, minor py3k updates were added: metaclass using
