Compatibility with GitHub-hosted runners

[cheahjs]

I was wondering what is the story like with GitHub-hosted runners. The current instructions require patching the runner, but this is done on disk prior to launch and is only feasible for self-hosted runners, but with GitHub-hosted runners, any steps that are run inside of a workflow are with an already running runner?

This might require patching the runner in memory - has anyone attempted this before?

It is probably not possible to use this cache server with Github hosted runners unless Github finally allows overwriting ACTIONS_CACHE_URL at runtime

Closing this for now (more info here actions/toolkit#1695)
