Review request for mesos and Vinod Kone.

Bugs: MESOS-5949

Repository: mesos


This field contains the time at which the master marked an agent as
unreachable. It will only be set for status updates (including
reconciliation updates) that describe tasks running on unreachable
(e.g., partitioned) agents.

The intent is to help frameworks decide how to handle tasks running on
partitioned agents: since the framework might have missed the initial
TASK_LOST/TASK_UNREACHABLE status update (e.g., due to framework
downtime/failover), it might otherwise be difficult for frameworks to
determine how long an agent has been partitioned.

This unreachable timestamp is stored in the registry and loaded as part
of master recovery.
