When many commits are discovered at once, import them at lower priority
Ref T13369. See that task for discussion.
When the discovery daemon finds more than 64 commits to import, demote the worker queue priority of the resulting tasks.
- Pushed one commit, ran bin/repository discover --verbose --trace ..., saw commit import with "at normal priority" message and priority 2500 ("PRIORITY_COMMIT").
- Pushed 3 commits, set threshold to 3, ran bin/repository discover ..., saw commist import with "at lower priority" message and priority 4000 ("PRIORITY_IMPORT").
