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
- [ ] Restart maven export for maven-central
- [ ] Add maven central to the standard listing
- [ ] Checks
