      Description

      the only way a replica can removed is by unloading the core .There is no way to remove a replica that is down . So, the clusterstate will have unreferenced nodes if a few nodes go down over time

      We need a cluster admin command to clean that up

      e.g:
      /admin/collections?action=DELETEREPLICA&collection=coll1&shard=shard1&replica=core_node3

      The system would first see if the replica is active. If yes , a core UNLOAD command is fired , which would take care of deleting the replica from the clusterstate as well

      if the state is inactive, then the core or node may be down , in that case the entry is removed from cluster state
