Plan (inspired by T4102):
- [X] Install scrubber (postgres) db (for production manually done) [1]
- [ ] D8034: Configure db connection (puppet)
- [ ] Check connection is ok
- [ ] Update documentation on how to connect to db
- [ ] Install schema in swh-scrubber db
- [ ] Grand read-only access to guest user
- [ ] Deploy postgres checker service on a dedicated scrubber node
