Review request for mesos and Niklas Nielsen.


Rebased, in preparation for part 2 (slave-side timeouts).

Bugs: MESOS-2110

Repository: mesos

Description (updated)

Added new --slave_ping_timeout and --max_slave_ping_timeouts flags
to mesos-master to supplement the DEFAULT_SLAVE_PING_TIMEOUT (15secs)
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.

Diffs (updated)

  src/master/constants.hpp c386eab 
  src/master/constants.cpp 9ee17e9 
  src/master/flags.hpp 6c18a1a 
  src/master/master.cpp f4b6463 
  src/slave/constants.hpp 761cfaf 
  src/slave/constants.cpp 83d9fc1 
  src/slave/slave.cpp a8b2621 
  src/tests/fault_tolerance_tests.cpp f927d4a 
  src/tests/partition_tests.cpp fea7801 
  src/tests/slave_recovery_tests.cpp 7e2e63d 
  src/tests/slave_tests.cpp e7e2af6 


Testing (updated)

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