[DMAAP] Use the common mariadb-galera instance

Have following updates for DMAAP-DR-PROV:
- Add section under .Values.global for shared mariadb instance default
info with a condition to instantiate local instance
- Add section under .Values for mariadb-init and mariadb-galera projects
- Add condition under requirments.yaml to install local mariadb instance
- Update deployment with DB host parameter and reflect it into resource
file (using the templates defined under templates/_mariadb.tpl)
