Create templates for global storage use
Two helper functions are defined: - common.storageClass: will print the right storage class according to properties set or not: * if no storage class set --> use previous behavior (storage class named `common.fullname-data`. * if a "persistence.storageClassOverride" is set for this specific chart, we use it (if it's "-", we set to default one) * if a "global.persistence.storageClass" has been set (and no storageClassOverride for this chart), we use it (same specificity than storageClassOverride) * if a "persistence.storageClass) has been set (and no storageClassOverride nor global one), we use it (same specificity than storageClassOverride) - common.needPV: will print "True" if we need a PV (no storageClass and storageClassOverride being set). an implementation example with mariadb-galera is provided.
