MDEV-20601: Make REPLICA a synonym for SLAVE in SQL statements 

Fix:
===
Add "REPLICA" as an alias for "SLAVE". All commands which use "SLAVE" keyword
can be used with new alias "REPLICA".

List of commands:

On Master:
=========
SHOW REPLICA HOSTS <--> SHOW SLAVE HOSTS
Privilege "SLAVE"  <--> "REPLICA"

On Slave:
=========
START SLAVE       <--> START REPLICA
START ALL SLAVES  <--> START ALL REPLICAS
START SLAVE UNTIL <--> START REPLICA UNTIL
STOP SLAVE        <--> STOP REPLICA
STOP ALL SLAVES   <--> STOP ALL REPLICAS
RESET SLAVE       <--> RESET REPLICA
RESET SLAVE ALL   <--> RESET REPLICA ALL
SLAVE_POS         <--> REPLICA_POS
