Description

Currently when there are duplicate documents in the RecordStore but no matching key in a unique index, validate repair mode is unable to insert the missingIndexEntry and thus unable to repair this in validate repair mode.

In this scenario, we might want to delete the duplicate document.

This feature is different from ~~SERVER-49507~~, which only deals with index rebuilds after salvaging data files.

Also, remove the TODO here.
