    Description

      Right now RM Epoch values in sub clusters are seeded in different ranges: 0, 1000, 2000, etc. If one RM restarts enough its epoch can increment until it clashes with a neighboring sub cluster. E.g. 999 -> 1000. To fix this, we introduce a configurable range by which the epoch generation is bound.
