Review request for mesos, James Peach, Vinod Kone, and Jiang Yan Xu.

Bugs: MESOS-7215

Repository: mesos


Master will not kill the tasks for non-Partition aware frameworks
when an unreachable agent re-registers with the master.
Master used to send a ShutdownFrameworkMessages to the agent
to kill the tasks from non partition aware frameworks including the
ones that are still registered which was problematic because the offer
from this agent could still go to the same framework which could then
launch new tasks. The agent would then receive tasks of the same
framework and ignore them because it thinks the framework is shutting
down. The framework is not shutting down of course, so from the master
and the scheduler’s perspective the task is pending in STAGING forever
until the next agent reregistration, which could happen much later.
This commit fixes the problem by not shutting down the non-partition
aware frameworks on such an agent.
