feat: backfill persistent grades during upgrade

In Olive, persistent grades are now mandatory. This was already the case in
Nutmeg, but it didn't mean that existing, non-persistent grades were migrated
to be persistent. This introduces a job that is run whenever a user upgrades
from Nutmeg. Alternatively, it can be run manually with:

    tutor local upgrade --from=nutmeg
