Description

Once we are sending acknowledgments through the master as per MESOS-1409, we need to keep terminal tasks that are unacknowledged in the Master's memory.

This will allow us to identify these tasks to frameworks when we haven't yet forwarded them an update. Without this, we're susceptible to MESOS-1389.
