Review request for mesos and Niklas Nielsen.


Bugs: MESOS-2150
    https://issues.apache.org/jira/browse/MESOS-2150


Repository: mesos-git


Description
-------

Added new --slave_ping_timeout and --max_slave_ping_timeouts flags
to mesos-master to replace the existing (still default) 
SLAVE_PING_TIMEOUT (15secs) and MAX_SLAVE_PING_TIMEOUTS (5).
   
These can be extended if slaves are expected/allowed to be down for
longer than a minute or two.
  
Beware that this affects recovery from network timeouts as well as
actual slave node/process failover.

Testing
-------

Manually tested slave failover/shutdown with master using different 
--slave_ping_timeout and --max_slave_ping_timeouts.
Updated unit tests to use shorter non-default values for ping timeouts.


Thanks,
