This completes the merging of server and client command processing.

Move client command handling out of TCP protocol (#7185)
The aim here is to move the command handling out of the TCP protocol classes and to also merge the client and server command handling (so that we can reuse them for redis protocol). This PR simply moves the client paths to the new `ReplicationCommandHandler`, a future PR will move the server paths too.

Remove connections per replication stream metric. (#7195)
This broke in a recent PR (#7024) and is no longer useful due to all
replication clients implicitly subscribing to all streams, so let's
just remove it.

Remove usage of "conn_id" for presence. (#7128)
* Remove `conn_id` usage for UserSyncCommand.

Each tcp replication connection is assigned a "conn_id", which is used
to give an ID to a remotely connected worker. In a redis world, there
will no longer be a one to one mapping between connection and instance,
so instead we need to replace such usages with an ID generated by the
remote instances and included in the replicaiton commands.

This really only effects UserSyncCommand.

* Add CLEAR_USER_SYNCS command that is sent on shutdown.

This should help with the case where a synchrotron gets restarted
gracefully, rather than rely on 5 minute timeout.

Move catchup of replication streams to worker. (#7024)
This changes the replication protocol so that the server does not send down `RDATA` for rows that happened before the client connected. Instead, the server will send a `POSITION` and clients then query the database (or master out of band) to get up to date.

Convert *StreamRow classes to inner classes (#7116)
This just helps keep the rows closer to their streams, so that it's easier to
see what the format of each stream is.

9ce4e344a8 Change device list replication to match new semantics.
Instead of sending down batches of user ID/host tuples, send down a row
per entity (user ID or host).

Propagate cache invalidates from workers to other workers. (#6748)
Currently if a worker invalidates a cache it will be streamed to master, which then didn't forward those to other workers.

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.
