Switched to @tryghost/logging instead of passing around the library. The main sticking points of this change are jobs. When jobs are launched we don't want them to use a separate @tryghost/logging instance because they would start parallel rotation jobs. @tryghost/logging v2.x passes all logs to the parent process if run in a child process, so that we can use the same patterns in jobs and the rest of the codebase.

* Replaces all references to isIgnitionError with isGhostError
* Switches use of GhostError to InternalServerError - as GhostError is no longer public
There are places where InternalServerError is not the valid error, and new errors should be added to the @tryghost/errors package to ensure that we can use semantically correct errors in those cases.
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- Ghosts existing boot process is split across multiple files, has affordances for outdated ways of running Ghost and is generally non-linear making it nigh-impossible to follow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
