 Allocates a new automatically generated port for a new project. If `project-name` is not provided, a default is calculated by the provided matcher. `project` is required if `--matcher=none`.

If `redirect` is specified, redirect to the server instead of reverse-proxying. See [here](#redirecting-instead-of-reverse-proxying) for more details.
