[mediawiki/core@master] Add statsv to edit recovery

https://gerrit.wikimedia.org/r/1005057

Ready for QA — unfortunately I only know how to check these are working using graphite (which has been shut down on the beta cluster, so I believe you need to use https://prometheus.wmcloud.org ?).

The metric names will be MediaWiki.edit_recovery.${ metric }.by_wiki.${ dbName }, where ${ metric } is either show (fired when the "Changes recovered" popup is displayed) or discard (fired when the "Discard" button of the popup is clicked).

Testing this on beta and inspecting the network tab, I see

• after recovering an edit a request to https://en.wikipedia.beta.wmflabs.org/beacon/statsv?MediaWiki.edit_recovery.show.by_wiki.enwiki=1c
• after discarding an edit a request to https://en.wikipedia.beta.wmflabs.org/beacon/statsv?MediaWiki.edit_recovery.discard.by_wiki.enwiki=1c

I believe this is correct.

I don't know how to use https://prometheus.wmcloud.org, so I couldn't check if the data appears there.
