refs https://linear.app/tryghost/issue/CORE-103/decouple-internal-frontend-code-from-url-module - By becoming a parameter in the routing bootstrap process URL is Service no longer a "require" inside the frontend controllers but rather becomes a part of the "internal API" of the bootstrapper. This is not the end form of it, rather a step closer to decouplint routing from the URL serivce. - The bootstrap module needs a facelift to have cleaner distinction between init/start methods. This is left for another time
