Fix URL schemes in dokku urls output

Previously, the presence of TLS certificates would cause `dokku urls` to
output all https URLs, even for domains which were not configured to use
TLS.

This change introduces a URLS file in the app's directory which contains
the URLs with schemes based on whether they have been configured to use
TLS in the nginx config.
