Support for protocol gs:// #661

will monocular support different protocols for hosting repositories ?. For example private repositories hosted directly on google buckets. Tried to add a not http record and got the following error:

time="2020-02-22T01:29:29Z" level=error msg="error requesting repo index" error="Get gs://foobar/test/index.yaml: unsupported protocol scheme "gs"" url="gs://foobar/test/index.yaml"

Is there any plan on the future to support this kind or different protocols ? Helm support adding repositories from gs://
