`repo clone`: interactive select of multiple options
When multiple logins are configured, running
tea repo clone gitea/tea (no hostname or
--login given) should result in a check on all logins if a repo with that name exists.
If multiple repos are available, start an interactive select prompt to choose the wanted option.
Ideally this mode would be entered only, if a (not yet existing) config preference
no_interact isn't set.
Deleting a branch is permanent. It CANNOT be undone. Continue?
