Data generator uses CSV imports for a massive speed increase, but
can't be used in some environments where SQL admin isn't
available. This allows us to set a flag to use the original
insert-based importer.

- Stored whether Docker is used in the config files
- When running `yarn setup`, any existing Docker container will be
reset. Run with `-y` to skip the confirmation step.
- `yarn setup` will always init the database and generate fake data
- Increased amount of default generated data to 100,000 members + 500
posts.
- Made lots of performance improvements in the data generator so we can
generate the default data in ±170s

This is a pretty huge commit, but the relevant points are:
* Each importer no longer needs to be passed a set of data, it just gets the data it needs
* Each importer specifies its dependencies, so that the order of import can be determined at runtime using a topological sort
* The main data generator function can just tell each importer to import the data it has
This makes working on the data generator much easier.
Some other benefits are:
* Batched importing, massively speeding up the whole process
* `--tables` to set the exact tables you want to import, and specify the quantity of each
