[infra] cdxgen repo is consuming too much build resources

[prabhu]

Like most open-source projects, the cdxgen project relies heavily on the generosity and free compute offered by GitHub for Actions. We are currently using up a significant level of compute, which would make it quite hard to migrate away from GitHub should a need arise.

The good news is that we now have three self-hosted agents, which are already operational. However, they are currently not utilised to their full extent, since many workflows are not working well under macos, and Linux virtualised using lima. Container builds for dotnet especially don't seem to work on macOS.

Last month

Last month, cdxgen repo has consumed over 50K build minutes.

Last 3 months

We have used a whopping 238K build minutes in the last 3 months.

We are also using up a lot of cache atm.

Cache usage doesn't seem to go down even after I manually deleted the large blobs. Any ideas?
