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.
