WIP: Remove unknown unreachable tasks when agent re-registers.
A RunTask messsage could get dropped for an agent while it's
disconnected from the master and when such an agent goes unreachable
then this dropped task message gets added to the unreachable tasks.
When the agent re-registers, the master sends status updates for the
tasks that the agent reported when re-registering and these tasks are
also removed from the unreachableTasks on the framework but since the
agent doesn't know about the dropped task so it doesn't get removed
from the unreachableTasks leading to a check failure when
this inconsistency is detected during framework removal.
