A function to ¨restart¨ the master-master replication in pi-appliance

[sepp67]

It could be useful to have an option in the pi-appliance to restart the master-master replication to avoid setting a new replication each time a database is disconnected. The function should do something like:

mysql> STOP REPLICA;
mysql> SET GLOBAL SQL_REPLICA_SKIP_COUNTER = 1;
mysql> START REPLICA;
