Clone respository fails to follow 308
Turns out HTTP 301 has a younger sibling 308 and GitLab uses it!
Using https://gitlab.com/esodan/gresg/
Builder reports an error instead of following the redirect to https://gitlab.com/esodan/gresg.git
to clone the repository
308 Permanent Redirect (RFC 7538) The request and all future requests should be repeated using another URI. 307 and 308 parallel the behaviors of 302 and 301, but do not allow the HTTP method to change. So, for example, submitting a form to a permanently redirected resource may continue smoothly.
