mariadb-operator has default setting "clusterName" that causes installs to fail on non-default named clusters

[shahzaib-bhatia]

Describe the bug
The mariadb-operator has a setting "clusterName: cluster.local" which is later used for galera nodes for their wsrep connection urls.
If this is not changed for a cluster with a different name galera will fail to come up due to name resolution failure.

Workaround when following wiki:

kubectl kustomize --enable-helm /opt/genestack/kustomize/mariadb-operator | sed "s/cluster\.local/${CLUSTER_NAME}/g"| kubectl --namespace mariadb-system apply --server-side --force-conflicts -f -
# persist changes
sed -i "s/^clusterName: .*$/clusterName: ${CLUSTER_NAME}/" /opt/genestack/kustomize/mariadb-operator/charts/mariadb-operator/values.yaml
