      Description

      Galeramon should be able to control which nodes are the preferred as the donor with the wsrep_sst_donor variable. This would allow joining nodes to choose "slave" nodes which will allow MaxScale to influence the donor choosing process.

      The monitor could execute SELECT @@wsrep_node_name; on a non-master node of the cluster and then assign the preferred SST donor node with SET GLOBAL wsrep_sst_donor=my_donor_node1.

      MariaDB [(none)]> select @@wsrep_node_name;
      +-----------------------+
      | @@wsrep_node_name     |
      +-----------------------+
      | localhost.localdomain |
      +-----------------------+
      1 row in set (0.00 sec)
       
      MariaDB [(none)]> set global wsrep_sst_donor = "localhost.localdomain";
      Query OK, 0 rows affected (0.00 sec)
