      Description

      The Desynced state of Galera Node is not given in maxctrl server list

      When Galera Node was desynced from the group with setting up wsrep_desync,
      the maxctrl is displaying just Running.
      It would be more clear if give in addition the Desynced state in the maxctrl server list.

      on server2 set wsrep_desync and FTWRL
      check that Node gets in Desynced state
      check the State of server2 from MaxScale Node via maxctrl list servers

      MariaDB [(none)]> set global wsrep_desync=1 ;
      Query OK, 0 rows affected (0.001 sec)
       
      MariaDB [(none)]> flush tables with read lock ;
      Query OK, 0 rows affected (0.000 sec)
      

      check locally on server2 the wsrep state

       
      MariaDB [(none)]> show status like "%state%" ;
