Introduce a request cache mechanism
Summary: Ref T8424. This adds a standard KeyValueCache to serve as a request cache. In particular, I need to cache Spaces (they are frequently accessed, sometimes by multiple viewers) but not have them survive longer than the scope of one request. This request cache is explicitly destroyed by each web request and each daemon request. In the very long term, building this kind of construct supports reusing PHP interpreters to run web requests (see some discussion in T2312). Test Plan: - Added and executed unit tests. - Ran every daemon.
