[WIP] Meta ticket too recap all the stuff pending and planning regarding the labs infra (we can always create more detailed subtasks)
- Repoint labsdb1001 and labsdb1003 to db1095 (T166546)
- Add and sanitize s2, s4, s5, s6 and s7 (T153743)
- Puppetize summary tables such as watchlist_count (maybe others?)
implement GTID (requires production changes)(only on sanitariums for now, done)- Implement a periodic check_private_data.py run (T153680)
Feel free to edit the description and add stuff
