ref PROD-233
- 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
