Title: Fix mongo multiple support instances

(Internal case: https://datadog.desk.com/agent/case/7447)

The aggregator was grouping all of the metrics from multiple mongo instances together because we weren't tagging by server or any other unique property per instance. This fix adds such tagging and fixes the issue with aggregation and calculating rates.

@remh Do you think there are any other checks that maybe have the same problem?
