    Description

      The current trigger design is simplistic and keeps all the intermediate state in memory. But this presents two problems when the overseer itself fails:

      1. We lose tracking state such as which node was added before the overseer restarted
      2. A nodeLost trigger can never really fire for the overseer node itself

      So we need a way, preferably in the trigger API itself to save intermediate state or checkpoints so that it can seamlessly continue on overseer restarts.
