Ctrl-Cing out of galera_new_cluster doesn't reset systemd environment

    Description

      Excerpt from /bin/galera_new_cluster:

      systemctl set-environment _WSREP_NEW_CLUSTER='--wsrep-new-cluster' && \
      		 
          systemctl start ${1:-mariadb}
      		 
       
      		 
      systemctl set-environment _WSREP_NEW_CLUSTER=''

      If the service start takes too long and the user aborts the script, the environment never gets reset and subsequent attempt to join this node to another primary component via `systemctl start mariadb` will instead bootstrap it.

            You'd still need to trap SIGINT in galera_new_cluster, otherwise the cleanup will not happen if the user aborts the script and service fails (and `ExecStartPost` won't get called)

            The solution https://github.com/MariaDB/server/pull/1143 in MDEV-19210 might resolve this as well, with a little improvements in the handling of the file in galera_new_cluster.
