e13c6c7a96 Handle one-word replication commands correctly 
`REPLICATE` is now a valid command, and it's nice if you can issue it from the
console without remembering to call it `REPLICATE ` with a trailing space.

c3e4b4edb2 Fix warnings about not calling superclass constructor 
Separate `SimpleCommand` from `Command`, so that things which don't want to use
the `data` property don't have to, and thus fix the warnings PyCharm was giving
me about not calling `__init__` in the base class.

6a519a0ca0 Remove vestigal references to SYNC replication command 
We've ripped pretty much all of this out: let's remove the remains.

Fix race in replication (#7226) 
Fixes a race between handling `POSITION` and `RDATA` commands. We do this by simply linearizing handling of them.

Move server command handling out of TCP protocol (#7187) 
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.

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.
