Correct cluster name check
When checking for failed states the cluster name is gathered using
stdout however the conditional is not checking stdout and is attempting
to split a hash which fails rendering an obscure error. This change just
makes the conditional look at stdout and split on a sting.

Fix the cluster state before re-running the playbooks. To ignore the

The galera_cluster_name variable does not match what is set in mysql.
Check your galera_cluster_name setting in your user_*.yml files in
"/etc/openstack_deploy" and compare to the current value in
"/etc/mysql/conf.d/cluster.cnf" on the host, and the "wsrep_cluster_name"
value set in your running galera cluster. To ignore the
cluster state set '-e galera_ignore_cluster_state=true'.
when:
- cluster_name.rc != 0
- (cluster_name.stdout.split()[-1] | default(false)) != galera_cluster_name
