Atlas Sharded Cluster Compatibility

[zhangyaoxing]

When running against Atlas sharded clusters, the permission doesn't allow us to directly connect to the shard nodes. Which leads to the following error

Failed to get execution result from atlas-vnfeuv-shard-0, member atlas-vnfeuv-shard-00-00.wy1z6.mongodb.net:27017: OperationFailure You are connecting to a sharded cluster improperly by connecting directly to a shard. Please connect to the cluster via a router (mongos). Command: listDatabases, Namespace: Foo, full error: {'ok': 0.0, 'errmsg': 'You are connecting to a sharded cluster improperly by connecting directly to a shard.

This happens to CollInfoItem and IndexInfoItem.
Find a workaround to fix the problem.

The listDatabase and listCollections command have been moved to the cluster level to avoid the problem. The $collStats and $indexStats, however, can't be moved. And is still causing the error.
