* $name:           ChangeReplicaType.java
* $description:    ChangeReplicaType.java is used to change a replica's type.
*                  If you change a replica's type to master, the current
*                  master replica will be changed to a secondary( Read-Write )
*                  replica. Trying to change a replica's type from master to
*                  any other type is not alowed and will cause 'Internal NDS
*                  Error'
