Slave removal: replace very few things in Sentinel.

SENTINEL REPLICAS was added as an alias, in the configuration rewriting
now it uses known-replica, however all the rest is basically at API
level of logged events and messages having to do with the protocol, so
there is very little to do here compared to the Redis core itself, to
preserve compatibility.
