      Description

      The distrib update processor should do sanity checks on incoming updates - you never know what greedy routers might hang to some packets for while before letting them go.

      We can quickly and easily check a couple things.

      If the update is from a Leader we can check that we don't currently think we are the leader (using a local isLeader state).

      If the update is from a Leader we can check that that leader matches what is in our current ClusterState.
