Don't remove existing entries from here, since old clients can still report
them. Just add the new ones.

The old interface was not being used by any apps aside from internal testing, so
in this case it's safe to remove. It won't appear in the wild.

Normally, I'd still push back, but given this whole histogram was added recently
and indeed it seems we don't have any data for that entry[1], I guess it's okay.

Note that external users can test out this API so we may still get data for this
in the future. But I don't think it's very important seeing as how we didn't
publicise it and it's going away now.

It depends on how critical it is -- UMA is not going to crash is it, if a data
point comes in that we don't have a handler for? I assume it just means we won't
record that data point, and since it will be at best a trickle, it can be safely
removed.
