Enable load balancing to Galera nodes in Donor state

    We use the wsrep_notify.sh script to notify changes in Galera cluster
    membership to haproxy. When xtrabackup was used for the state transfer,
    nodes in the Donor state would be included in the backend pool. However,
    since the switch to mariabackup in the Stein cycle, we now remove nodes
    in the Donor state from the backend pool.

This change ensures that nodes in the Donor state are included in the
backend pool when the SST method is either xtrabackup or mariabackup.
