Allow to invite a top-group in a sub-group or project

Release notes

Problem to solve

As a GitLab.com group owner for my company, I would like to be able to invite my top-group in a sub-groups or a project to modify default permission level in it.

It would allow me to grant developper access, for instance, to every top-group member in a project or a group of projects.

Intended users

User experience goal

Proposal

Allow top-group selection in "Invite Group" of projects & sub-groups.

Further details

I have a 100+ developers organized in teams : every team has its own sub-group. Some teams needs to share projects or sub-sub-groups with everyone. The only available option is to invite every sub-group.

What does success look like, and how can we measure that?

What is the type of buyer?

Is this a cross-stage feature?
