support for https git remotes

[selfisekai]

ssh interface is disabled on some instances and they need to use https the whole time. on repos like this, git gr upload fails like this:

Error:   × Failed to parse Gerrit configuration from Git remotes. Tried to parse these remotes:
  │ • https://chromium.googlesource.com/chromium/src

Hm, OK. What's the remote URL look like in this case?
