repository/group wildcard

[andreascian]

I think that it might be interesting to allow label management (copy/update) for more than one project/group (or even a whole GitLab instance) at once.

E.g.

gitlab-cli label copy -U https://mygitlab.example.com/mygroup/*  -t xxxxxx

gitlab-cli label copy -U https://mygitlab.example.com/mygroup/linux-*  -t xxxxxx

gitlab-cli label update -r "linux-*" --match <REGEX> --name <NAME> --color <COLOR> --description <DESC>

WDYT? Any clue in how to add this feature?
