This test checks that the federation sender is correctly sending back

FEDERATION_ACK messages. The test works by spinning up a federation_sender

worker server, and then fishing out its ReplicationCommandHandler. We wire

the RCH up to a mock connection (so that we can observe the command being sent)

and then poke in an RDATA row.

XXX: it might be nice to do this by pretending to be a synapse master worker
|

(or a redis server), and having the worker connect to us via a mocked-up TCP

transport, rather than assuming that the implementation has a

ReplicationCommandHandler.
