Enhance MySQLDown alert

[JustHumanz]

Due to MySQLDown being very noisy even the mysql cluster still running above minimal replication, so we need to enhance it

this pr will replace the MySQLDown with MysqlClusterDown, MysqlClusterDown have two severity P3(warning) and P5(info). i.e when we have 5 percona-xtradb and only 1 replication down it only trigger MysqlClusterDown with P5 because the mysql cluster still can operational normally but if we lost 3 replication(which means there only 2 replication) it will trigger MysqlClusterDown with P3 since mysql cluster unable to operate
