[COMMON/VID] Modified VID to use Shared DB.
This change modifies VID to use the shared DB instance of mariadb. In addition, we create a mechanism in mariadb-init to allow a shared DB user to run a script after the DB has been created. The script can be passed as a configMap (as is the case with VID) or it can be a standalone script that is passed as a string.
