Update usage ping data to track usage of DiffNotes
Problem
The performance indicator for groupsource code is MR usage. Users who comment on diffs are considered MR users, however, this is not currently tracked by usage ping.
Proposal
Add DiffNote usage to usage ping. This should help us answer the question: How many unique users have used DiffNotes
?
