    Delete sg rule which remote is the deleted sg

    Based on bug #2008712 if we have a security-group which
    is the remote group of a 2nd security-group, the backend
    never deletes the rule of the 2nd group which
    remote_group_id is the original security-group.
    By AFTER_DELETE event for each rule that has the
    security_group_id as remote_group_id, we can make the
    mech drivers do their work and delete these rules in the
    backend.
