Handle replication commands synchronously where possible (#7876)
Most of the stuff we do for replication commands can be done synchronously. There's no point spinning up background processes if we're not going to need them.

Track command processing as a background process (#7879)
I'm going to be doing more stuff synchronously, and I don't want to lose the
CPU metrics down the sofa.

Fix Redis reconnection logic (#7482)
Proactively send out `POSITION` commands (as if we had just received a `REPLICATE`) when we connect to Redis. This is important as other instances won't notice we've connected to issue a `REPLICATE` command (unlike for direct TCP connections). This is only currently an issue if master process reconnects without restarting (if it restarts then it won't have written anything and so other instances probably won't have missed anything).

Richard van der Hoff 7f7eedbebb Wait for a POSITION on the right connection before accepting RDATA
... otherwise we can believe we're up to date when we're not.

Fix redis password support. (#7401)
We forgot to set the password on the subscriber connection, as well as
not calling super methods for overridden connectionMade/connectionLost
functions.

Don't relay REMOTE_SERVER_UP cmds to same conn. (#7352)
For direct TCP connections we need the master to relay REMOTE_SERVER_UP
commands to the other connections so that all instances get notified
about it. The old implementation just relayed to all connections,
assuming that sending back to the original sender of the command was
safe. This is not true for redis, where commands sent get echoed back to
the sender, which was causing master to effectively infinite loop
sending and then re-receiving REMOTE_SERVER_UP commands that it sent.

The fix is to ensure that we only relay to *other* connections and not
to the connection we received the notification from.

Fixes #7334.
