Adjust mongodbmetricsqueryExecutorscannedObjects and mongodbmetricsdocumentreturned metrics with dimension of namespace, query and collection. So alerting on them could be more flexible.
For example, on our production we have queries which run once in a long time and it is expected for them to have high ration of Scanned to Returned. But other queries which are running constantly should be on default low values. As now we can set alert only on cluster level -> It results in a lot of FPs.

In general a lot of other metrics could win from additional dimensions in them.

Thank you in advance for implementing
