Adds validation to make sure Redis has been setup with the supported eviction policy to avoid surprises when cache suddenly is inconsistent.
This PR replaces #34178, and instead of checking in constructor and throwing it only checks on save, warns about this and refuses to save cache as suggested on the other PR.
TODO:
- [x] ~Adapt test setups for this to set correct eviction policy~ _It already uses default noeviction_
