Create cache for GitHub Actions

[tonynajjar]

I'm almost sold on using Ubicloud over other alternatives like e.g. https://github.com/runs-on/runs-on but I'm missing this important caching feature and it seems like they implemented it or at least part of it. I hope Ubicloud implements it 🙏. If you can already share a rough timeline of that feature that would be helpful

I'm currently evaluating running actions on ubicloud and ran into an issue with the actions cache.

Our bundler cache is ~650MB, and the download from the default cache location runs at 8-10 MB/s. The cache restore takes ~90s. A clean install takes ~95s, so there is very little benefit to caching at the moment.

Thanks for the support with GitHub Actions. I have a slightly different use case concerning caching.

We use the bazel remote cache server to cache bazel builds and share them across CI runners. It would be beneficial for us to be able to:

• Decide in which region the GitHub Action Runners are executed

If we know that the GitHub Runners are operating in the German region, we can deploy a VM with the bazel remote cache server in the same region.
