Currently the evaluations have a fixed Nack timeout period of 60 seconds. If they do not complete, the eval broker will always cause a Nack to happen. This is probably fine, except for under high contention or high load situations where its possible to exceed that timeout. This PR causes the Nack timer to be reset if the scheduler is submitting plans or modifying evaluations, as this still proves the liveness of the scheduler. It is still possible for an extremely slow scheduler to hit the Nack timeout, but this should make it much less likely.
