Set the cache autodelete cycle

[95jinhong]

Hi, I have configured a self-hosted runner on top of EKS for NPM and Gradle builds.

Thanks to the above project, I really appreciate the easy of using cache :) When using the Cloud Cache, it is removed after 7 days of inactivity, but the corresponding Local Cache does not seem to be deleted after 7 days. Is it possible to support a deletion policy for unused cache?

Thanks you
