  * get status for one server
 $prog -a status -s vm1
  * create first slave server and all accounts for bx cluster work
 $prog -s vm2 -a slave --cluster_password="XXXXXXXXXXX" --mysql_password='YYYYYYYYYYYYY' --replica_password="ZZZZZZZZZZ"
  * change master server
 $prog -a master -s vm2
  * delete slave server
