Subject: [PATCH] Made Content API caching configurable

refs https://github.com/TryGhost/Toolbox/issues/411

- Having hardcoded cache control values in the codebase makes it impossible to experiment with new values without a version release.
- Having all values configurable by default will allow for easier caching experiments and customizations on self-hosting instances.
