Granting privileges and roles commonly

The common privilege is a privilege that can be exercised across all containers in a container database. Depending only on the way it is granted, a privilege becomes common or local. When you grant a privilege commonly (across all containers) it becomes a common privilege. Only common users or roles can have common privileges. Only common role can be granted commonly.
