Plan:
- [x] Deploy maven indexer exporter services (one per maven indexes: maven-central, ...)
- [x] Deploy frontend to expose maven indexer exporter results (*.fld files)
- [x] Deploy maven worker services: lister + loader
- [x] scheduler (saatchi): Restart swh-scheduler-schedule-recurrent service (so maven tasks are scheduled)
- [x] Add maven central so maven exporter scrapes its index and export it
- [x] Discover it failed (out of disk space) due to a forgotten step ¯\_(ツ)_/¯
- [x] T3746#82956: Prepare maven-exporter node to have enough disk to receive indices
- [x] Restart maven export for maven-central
- [x] T4330#90727: Wait for the end of it ^...
- [x] T4330#90730: Add maven central to the standard listing once ^ is done
- [ ] D8421: Make sure lister workers consume the maven queues
- [ ] Checks
