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
