Rejecting Index Suggestions
Some Index Suggestions don't work. The Performance Advisor doesn't sample data, and therefore can not predict if some field is worthwhile in an index or not (e.g. some fields may contain the same value for all documents).
If we decide to not apply the Index Suggestion, or we apply it, test it, and remove the Index again because it's not being used by MongoDB, the Index Suggestion is still showing up. It can also trigger alerts.
Please add the possibility to reject an index suggestion, so that it's hidden from the UI and can not trigger alerts.
