Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 9b0adea0769b026875ee312d223960c559c700bb
  - Merge "Create templates for global storage use"
  - 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.
