        reservation.

        Currently a resource (project, folder, organization) can only
        have one assignment per each (job_type, location) combination,
        and that reservation will be used for all jobs of the matching
        type.

        Different assignments can be created on different levels of the
        projects, folders or organization hierarchy. During query
        execution, the assignment is looked up at the project, folder
        and organization levels in that order. The first assignment
        found is applied to the query.

        When creating assignments, it does not matter if other
        assignments exist at higher levels.

        Example:

        -  The organization ``organizationA`` contains two projects,
           ``project1`` and ``project2``.
        -  Assignments for all three entities (``organizationA``,
           ``project1``, and ``project2``) could all be created and
           mapped to the same or different reservations.

        "None" assignments represent an absence of the assignment.
        Projects assigned to None use on-demand pricing. To create a
        "None" assignment, use "none" as a reservation_id in the parent.
        Example parent:
        ``projects/myproject/locations/US/reservations/none``.

        Returns ``google.rpc.Code.PERMISSION_DENIED`` if user does not
        have 'bigquery.admin' permissions on the project using the
        reservation and the project that owns this reservation.

        Returns ``google.rpc.Code.INVALID_ARGUMENT`` when location of
        the assignment does not match location of the reservation.
