GitHub Importer - Map GitHub Teams to GitLab during import
## Problem to Solve
[GitHub Teams](https://docs.github.com/en/organizations/organizing-members-into-teams/about-teams) are currently not migrated during import from GitHub into GitLab.
## Proposed Solution
Consider importing Teams as Member-only subgroups. The concern with this solution is that GitHub Teams have a many-to-many relationship with repositories, while in GitLab, there is a 1-to-1 relationship between a project/subgroup and a repository.
A potential solution would be that we perform a "partial" import, where Teams are imported as subgroups, but those subgroups are "independent" from the projects that contain the repositories.
