Extend session keepalive

Browse Source 
Since the keepalive is retried, there's no reason to try
to be as frequent as half the specified interval.  The
spec allows inactivity timeout as short as 57 seconds, so
the keepalive interval is extended to 50-55 (allowing some
room for retry to hit in case of dropped packet).
