Review request for mesos and Vinod Kone.
Bugs: MESOS-6445
https://issues.apache.org/jira/browse/MESOS-6445
Repository: mesos
Description
-------
If the master fails over and an agent does not re-register within the
`agent_reregister_timeout`, the master marks the agent as unreachable in
the registry and sends `slaveLost` for it. However, we neglected to
update the master's in-memory state for the newly unreachable agent;
this meant that task reconciliation would return incorrect results
(until/unless the next master failover).
