    Added test for reattached security groups

    We had a bug for OSP13 with openvswitch firewall driver that the established
    connection can't be resumed after the security group has been removed from
    the port and than added back. Need to test this behavior.

    In order to keep the connection open there is a new StatefulConnection
    class
