Clean up ShardedWorkerHandlingConfig (#9466)
* Split ShardedWorkerHandlingConfig

This is so that we have a type level understanding of when it is safe to
call `get_instance(..)` (as opposed to `should_handle(..)`).

* Remove special cases in ShardedWorkerHandlingConfig.

`ShardedWorkerHandlingConfig` tried to handle the various different ways
it was possible to configure federation senders and pushers. This led to
special cases that weren't hit during testing.

To fix this the handling of the different cases is moved from there and
`generic_worker` into the worker config class. This allows us to have
the logic in one place and allows the rest of the code to ignore the
different cases.

"""A FEDERATION_ACK should be sent back after each RDATA federation
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.
