[NBI] Use the common galera cluster of ONAP

Instead of having our "own" galera cluster, use the common one already
proposed by OOM.
If a local cluster is needed, you just need to set
global.mariadbGalera.localCluster to True.

Also create a common chart that create the needed values for the
database.
