Allow git pull/push on project redirects

IMPORTANT: This MR needs this gitlab-shell branch in order to work properly

What does this MR do?

Allow git pull/push on a repository after it was renamed

Are there points in the code the reviewer needs to double check?

• Different scenarios with permanent and temporal redirects
• Compatibility with gitlab-shell

Why was this MR needed?

To let old git url's of redirected projects continue to work. Now it displays a redirect warning message when that happens instead of rejecting the push/pull

Screenshots (if relevant)
