* Update docs/submodules/oom.git from branch 'master'
  to 83d278baef5b1de142c29935438bac38372fc888
  - Merge "[NBI] Use mariadb-galera from common"
  - [NBI] Use mariadb-galera from common

    Instead of using "homegrown" mariadb chart, move to use the common
    mariadb-galera chart in order to be aligned with most of the other users
    of mariadb and eventually to move into the common mariadb galera
    instance.
