Background: - Ghosts existing boot process is split across multiple files, has affordances for outdated ways of running Ghost and is generally non-linear making it nigh-impossible to follow - The web of dependencies that are loaded on boot are also impossible to unpick, which makes it really hard to decouple Ghost - With 4.0 we want to introduce a new, linear, simpler, clearer way to boot up Ghost to unlock decoupling Ghost into much smaller pieces This commit: - adds a new ghost.js file which switches between boot mode with `node index` or `node index old` so that if we find bugs we can work around them this week - Note: the old boot process will go away very soon, but ghost.js will remain as the interface between the command to start Ghost and the application code - reworks the database migration process into a standalone utility, so that the DB is handled as one simple step of the boot process, decoupled from everything else - is missing tests for this new db utility - leaves a lot of work to do around loading core code, services, express apps in a sensible order, as work to fix this would start to break the old boot process - doesn't use the new maintenance app because we aren't restarting the server here, instead we have the concept of a "core app" that starts in maintenance mode - need to think about how apps will be decoupled in the near future
