In file cluster_check_metadata_consistency_cmd.cpp, in method _runClusterLevel, we call a helper function getAllDbPrimaryShards here.
For all shards that this function returns, we create a request object.

This function currently unconditionally returns the config shardId, caused by this code.

The _runClusterLevel then unconditionally adds a connection to the config shardId again a few lines later here.
As a result, we create multiple cursors to the config shard when running this command.
This seems unnecessary.

We should change it so that only one cursor is opened for the config shard.
