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.
