Support Group-level and Project-level variables.

It would be nice to support Group-level and Project-level variables:

https://docs.gitlab.com/ee/api/project_level_variables.html

Keep up the excelent work.

@Lasering
Support for both project and group variables has been added and released in 4.9.22. Please verify and close this issue when you have a chance.

That was the fastest I've ever seen someone add a new feature in a open source project. Kudos to you sir.
