Remove usage of deprecated logger.warn method from codebase (#6271) 
Replace every instance of `logger.warn` with `logger.warning` as the former is deprecated.

Remove unnecessary parentheses around return statements (#5931) 
Python will return a tuple whether there are parentheses around the returned values or not.

I'm just sick of my editor complaining about this all over the place :)

015b3622eb Skip building a ROW_TYPE when building updates 
We're about to turn it straight into a JSON object anyway so building a
ROW_TYPE is a bit pointless, and reduces flexibility in the update_function.

Fix ClientReplicationStreamProtocol.__str__ (#4929) 
`__str__` depended on `self.addr`, which was absent from
ClientReplicationStreamProtocol, so attempting to call str on such an object
would raise an exception.

We can calculate the peer addr from the transport, so there is no need for addr
anyway.

313987187e Fix tightloop over connecting to replication server 
If the client failed to process incoming commands during the initial set
up of the replication connection it would immediately disconnect and
reconnect, resulting in a tightloop.

This can happen, for example, when subscribing to a stream that has a
row that is too long in the backlog.

The fix here is to not consider the connection successfully set up until
the client has succesfully subscribed and caught up with the streams.
This ensures that the retry logic timers aren't reset until then,
meaning that if an error does happen during start up the client will
continue backing off before retrying again.

b13836da7f Remove conn_id from repl prometheus metrics 
`conn_id` gets set to a random string, and so we end up filling up
prometheus with tonnes of data series, which is bad.

0e8d78f6aa Logcontexts for replication command handlers 
Run the handlers for replication commands as background processes. This should
improve the visibility in our metrics, and reduce the number of "running db
transaction from sentinel context" warnings.

Ideally it means converting the things that fire off deferreds into the night
into things that actually return a Deferred when they are done. I've made a bit
of a stab at this, but it will probably be leaky.

f59be4eb0e Fix unit tests 
on_notifier_poke no longer runs synchonously, so we have to do a different hack
to make sure that the replication data has been sent. Let's actually listen for
its arrival.

warnings, and will help with our metrics.
