Change the replication settings.
<p>
The SLAVEOF command can change the replication settings of a slave on the fly. If a Redis
server is already acting as slave, the command SLAVEOF NO ONE will turn off the replication
turning the Redis server into a MASTER. In the proper form SLAVEOF hostname port will make the
server a slave of the specific server listening at the specified hostname and port.
<p>
If a server is already a slave of some master, SLAVEOF hostname port will stop the replication
against the old server and start the synchronization against the new one discarding the old
dataset.
<p>
The form SLAVEOF no one will stop replication turning the server into a MASTER but will not
discard the replication. So if the old master stop working it is possible to turn the slave
into a master and set the application to use the new master in read/write. Later when the other
Redis server will be fixed it can be configured in order to work as slave.
