feat(ops): configure depot replication to sanduny r/4274

this configures gerrit's built-in replication plugin to push every
change in depot to sanduny.

this allows us to serve a replica of depot from sanduny.

manual config that was needed which needs to be automated:

* system-wide known_hosts does not work, needed one in /var/lib/git
* .ssh/config MUST be present and configured for sanduny.tvl.su
