Find a new solution for Cerbero deps storage
egress is expensive on CI and cerbero deps account for over 1T of egress per month. We need to find a better solution to that. I believe we have two options:
- Implement local storage on runners, ideally non-growing so it does not get removed all the time
- Upload cache to an external server for which egress is inexpensive.
I'd like feedback on this, and ideally someone to jump in an implement such a solution.
