Is your feature request related to a problem? Please describe.

Cluster Name is a very useful attribute to have when identifying issues using MongoDB Atlas metrics.

Describe the solution you'd like

As noted in the client in code, the API does not draw the connection for you from Process (mongod/mongos) to Cluster, but the connection can be easily drawn by using the Cluster's MongoURI and the Process's UserAlias.

"mongo_uri": "mongodb://host1.mongodb.net:27017,host2.mongodb.net:27017,host3.mongodb.net:27017"

"user_alias": "host1.mongodb.net"

Describe alternatives you've considered

There does not appear to be a way in the Atlas API to connect these objects and appropriately label the metrics emitted without using the mentioned connection.

I will make this default-disabled, like the user_alias addition in #18881

Closing as fixed, thanks!
