Review request for mesos and Vinod Kone.


Changes
-------

Address review comments.


Bugs: MESOS-5396
    https://issues.apache.org/jira/browse/MESOS-5396


Repository: mesos


Description
-------

If the agent observes that the boot ID has changed since the last time
it successfully (re-)registered with the master, we know that any agent
IDs that were previously in use in this `work_dir` must be associated
with different boot IDs; hence, any executors/tasks associated with
those agent IDs are no longer running, and those agent ID will never
attempt to re-register with the master. The agent now reports these
retired agent IDs to the master; the master will later take advantage of
this information, e.g., to learn that an agent that we think might
re-register after master failover will never re-register.
