- this switches the monorepo over to using Nx instead of Lerna, because
we don't currently need the versioning+publishing capabilities
- this also adds an `nx.json`, which allows us to enable task caching
- also adds `build:ts` to the TS projects, which is cached for fast execution
- how these interact with the dev.js script will hopefully soon be
reworked to be a better experience

- this moves the bulk of the tsconfig file to the `ghost/` folder and
simply extends this file in each of the TS lib packages we currently
have
- this makes it a lot easier to make single changes to our TS config

- This is a convenience method that should allow fetching collections by their slug. It is a great developer experience for in case when fetching built-in collections like "featured" and "index", so can avoid an extra call to find the collection and it's ide one wants to use.
This is the first pass at an abstract class for our in-memory repository
implementations. It's based off of the existing implementations and
should speed up local development and deduplicate code
