[COMMON][MARIADB] Upgrade Mariadb DB galera version

Mariadb DB Galera containers version is outdated and unmaintained. We
need them to move to a new image provider.
As new image provider is not compatible with our old templates, we
also update the templates (by reworking bitnami mariadb-galera chart).
An update of global mariadb image is also done in order to match mariadb
galera version.
