builds url discovery (#334)

- Feature: Added `--host` option to use Jupiters list of cloud host and zen servers to resolve best hosts
- Feature: Use local zenserver as builds cache if it has the `builds` service enabled and `--cloud-discovery-host` is provided and no remote zenserver cache hosts can be found
- Improvement: Added `--override-host` option as a replacement for `--url` (`--url` still works, but `--override-host` is preferred)
