This task tracks the implementation of splitting Thanos components from its current home (`thanos-fe*` hosts). In other words, leaving thanos-fe / thanos-be to purely run Swift for storage. The new hosts and role will be named `titan`
The following steps are @fgiunchedi's proposal on how to proceed:
* [x] Decide on a name for the hosts/project (This is by far the hardest part. Filippo' suggestion are sth related to MCU's Thanos, for example anything short will do: `vision`, `tony`, `glove`, etc)
* [ ] Procure hardware: T341237 T341236
* [ ] Create new puppet roles to run Thanos only and apply the role to the new hosts (T341999)
* [ ] Pool the new hosts for `thanos-query` LVS service **only**, verify queries can be served as expected (T341999)
* [ ] Depool the thanos-fe hosts from `thanos-query` LVS service
* [ ] Clean up the existing puppet role `thanos::frontend` in a way that removes Thanos bits from existing hosts
