Which problem is this feature request solving?

Hi,
Now, cloudquery can not get member info from gitlab when using gitlab saas.

I think saas user and company rate is getting bigger, so cloudquery can handle and provide the all information using api.

Describe the solution you'd like

how about get company's top level group name for variable?

In my case,
gitlab.com/company is top level group,
and I can get all users info using billable_members api.

I think this can be useful instead of member table.
