This PR will also refactor generated project CLI serve command to use --bind instead of --host and --port for compatibility sake with gunicorn. Implementing #25 should be easier now. However, env variables FASTAPI_HOST FASTAPI_PORT will need to be refactored to FASTAPI_BIND as well.

EDIT:
Also currently there is no validation for the --bind option. However, this will be done by gunicorn anyways. I wonder if it's really that needed to validate it in click.Option callback.
