    Cleanup deleted load balancers in housekeeper's db_cleanup

    When load balancer is deleted the corresponding DB entry is marked
    as DELETED and is never actually removed along with a VIP
    associated whit this load balancer.

    This adds a new method to db_cleanup routine that scans the DB for
    load balancers with DELETED provisioning_status and deletes them
    from db if they are older than load_balancer_expiry_age. Corresponding
    VIP entries are deleted in cascade.

    Added new config option `load_balancer_expiry_age` to the `house_keeping`
    config section.

    Also changed the default value of exp_age argument to
    CONF.house_keeping.amphora_expiry_age in check_amphora_expiry_age
    method.
