+1 maintenance report

[Matthias Klose]

afk on Thursday and Friday, doing +1 instead on Monday and Tuesday...

 - no-change uploads for a handful of transitions
   imported by Debian syncs.
 - while the autopkg testers were idle, gave back
   some tests to let those migrate.
 - finally got acceptance to override any failures
   triggered by python3-defaults (but only after
   running 2k tests over the weekend for no reason).
   we don't want to test with 3.8 anymore.
 - uploaded python3-defaults dropping 3.8, and did
   the 3.8-dropping no-change uploads (after asking
   if other transitions were pending).
 - spent most of the Tuesday retrying some dozen
   builds without a build log, the only new ones
   some riscv64 issues with semop(1) failures (reported
   those).
 - cleanup of -proposed for old binaries left.

The autopkg testers are busy now, however there are again more transitions
synced from Debian which need attention this week.
