Changes

This PR adds support for skipping cache when cache-control response header miss the public value.

Since it doesn't make too much sense for repository cache, it's disabled.

But for package-level caching it's important to separate private packages, so it's enabled for package cache provider by default.

I think we should allow caching if the header is missing 🤔

we should first add some logging and track some stats in the hosted app. so we're sure most ecosystems behave properly. and if not we need config options to workaround.
