incubator-geode git commit: GEODE-762: change default setting for enable-network-partition-detection

Repository: incubator-geode
Updated Branches:
  refs/heads/develop 0705e85cd -> 3897a76ea


GEODE-762: change default setting for enable-network-partition-detection

This setting now defaults to being turned on.  Some unit tests that perform
HA operations have been modified to disable it.
