Support min-age in render caching

Problem/Motivation

All the new render cacheing API is nice, but there is a full level of usecases where you want to ensure that a cache entry is not constantly invalidated.

Views expose that information via time based caching.

Proposed resolution

Discussed with plach at the airport:

For 3. we will need a #cache_minage property (that does not bubble and hence is not within #cache), which controls that the RenderCache service should set that special flag for retrieving the cache, so that invalid / expired items are returned.

Will likely need some more thought as we do not want to call the cache plugin at all, but determine on cache retrieval, so we probably should be setting that always and then check if that property is present in the retrieved render array.ù

If it is set and invalid, we compare the timestamp of the minage with the actual age timestamp, else we return a cache miss.

--

- None plugin should just set max-age 0 and we are done.

- Tag based output kinda does nothing on itself. (what we already do in core except that we remove the old and now due to bubbling broken output cache support)

Based upon that we need to figure out the proper details.
