- Settings Manager used to store all of it's settings values in a hash - an in memory cache in disguise. Having a hidden cache made it hard to reason about it's impact of memory usage and did not allow to swap it out for an alternative storage metchanism easily. Having a cache storage abstraction in Settings Manager allows to get rid of long lasting memory problems + decouples storage mechanism from the logic around transforming stored values.

- Passing "cache" through constructor did not work out because cache setting is still dependent upon on the model layer (gets called before it has a chance to initialize during db migrations)
- To remove the initialization dependency blockers were:
"defaults" method in the post model - the value resolved to "undefined" anyway during the fixture insertion
validate-password module - checks the password against "undefined" during fixture initialization
- Passing the cache through "init" method works too, but is not as clear as with constructor DI pattern.

- This is a groundwork which moves the "cache" property in settings cache to be injectable parameter, so we can swap it out with different implementations.
- The module will be broken downn into two concepts - an injectable cache and a cache manager (the update system)

- this commit turns the Ghost repo into a monorepo so we can bring our
internal packages back in, which makes life easier when working on
