      Description

      We should have a policy to the effect of "maxShardsPerHost=1" by default.

      I created a 4 node cluster , created lots of collection on node1 and node2.

      Then used the suggestions to move replicas. I ended up with a scenario where both replicas of a collection was on one node.

      So if we create a policy such that this can never happen as maxShardsPerHost=1 was the default

      {"replica": "<2", "shard" : "#EACH" , "node" :"#ANY", "strict" : "false" }
