[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.
