Subject Review Request 25567: Hold on to unacknowledged terminal tasks in the Master.

Review request for mesos, Niklas Nielsen and Vinod Kone.

Bugs: MESOS-1410

Repository: mesos-git


This is the MESOS-1410 which fixes MESOS-1389.

The idea here is that the master needs to hold on to those tasks that are terminal, but have
yet to be acknowledged by the scheduler. Otherwise, reconciliation requests could lead to
TASK_LOST updates **before** a framework receives a terminal TASK_FINISHED/TASK_FAILED/etc
update for the task.

Now the master needs to:
(1) Remove tasks when an acknowledgement arrives.
(2) Recover resources when the task becomes terminal.
(3) Omit resources for terminal tasks in the http statistics.
