Don't use cross-cluster reprioritization locks; instead, just clear out priorities whenever we'd normally be doing that.

Use reprioritization tracker to make sure reset happens as a consistent whole.

No longer track a timestamp in reprioritizationtracker

Use database fields to permit multiple reprioritization threads to be active at the same time, cross cluster.
