    Retry on routerport delete race
    
    After deleting the router interfaces, another concurrent
    process (e.g. HA port creation) could happen before the actual
    router is deleted, which would lead to an SQLAlchemy error due
    to the relationship being violated.
    
    This patch fixes the issue by bumping the router revision before
    deleting the router to check for concurrent interface additions.
    A race will trigger a staledataerror which will be retried by
    the decorator
