Backoff strategy

If the RetryCount property is set to true, and the probe fails to establish a connection or loses an existing connection to the device, it reverts to a backoff strategy. The probe uses backoff strategy as mentioned (1s, 2s, 4s etc) if RetryInterval is set to 0. If RetryInterval > 0, the probe will retry at a fixed interval period. Once the connection is made to the CORBA interface, the probe tries to log in to the device. If the probe fails to log in, it shuts down and tries to connect again. The backoff strategy remains in place until a successful login occurs.
