persistent cache in CI

[KieranFleckney]

Firstly I am thankful you forked this project. I was looking using earthly before then stopped.

My question is, how do you persiste cache state between runs when using a ci like github action or azure devops pipeline. Is there a easy way to do this. I know there was a buildkit cache experimental feature but don;t know if there still works. or do you need to use remote runner? Maybe there is no solution currently but I can't see any issue/discussion about it currently and I know the docs a still work in progress.

Any information would be helpful
