Make `CachingSession` respect SAPI's `Cache-Control`/`max-age` (when released) #646

In #645 we use a hard-coded default value for max-age (15 min), and validate cache via conditional requests after that.

That's because SAPI currently doesn't implement cache control, i.e. it returns none of the Cache-Control, Expires or Last-Modified header fields.

Implement support for Cache-Control response field, as that's the most modern and most robust cache control mechanism.
