This will break all historical queries for self-profile data, right? Do we want to perhaps query for both or some other mechanism to not do that?

An alternative could be to first refactor self profile management (#1896), so that we can e.g. version it, and then have some logic to detect if the archive has the old (walltime) or new (icount) version, and perform the query base on that.
But I'm not sure if people really look at old self-profile results at all, usually we're only interested in them for a brief moment after/before a PR is merged.

This is a second attempt to land #1647, which was later reverted in #1700.
I tried to manually SSH into the collector server and run the whole benchmark suite with
--self-profileusing icounts. It went through. I'd like to try this on the live server to see what happens. If it fails again, we'll know more to see where we should investigate the failure.
