      It would be very helpful for clients, like replication or sharding, to track collection via a unique id which doesn't change during a rename or restarts. The "id" should be the same across replicas in a set or shards in a sharded cluster. Note: There is already an _id in sharding metadata for a collection but that is not exposed.

      Here is an example of output from listCollections with an "id":

      > db.runCommand("listCollections")
      {
      	"collections" : [
      		{
      			"id" : NumberLong("70368744177664"),
      			"name" : "system.indexes",
      			"options" : {}
      		}
      	],
      	"ok" : 1
      }
