Proposal: Extend gitlab_project_members to support Group invitations

[Acarnesecchi]

Summary

Context

In our current workflow, we automate the creation of repositories and immediately invite relevant teams to these repositories. We manage permissions and accesses through group assignments, which aligns well with GitLab's capability of inviting groups directly to projects.

Problem

The existing gitlab_project_members module only supports adding individual users to projects, which is not ideal when dealing with large teams that are already organized into groups within GitLab. While I could simply get the group's members and add them individually with their respective access level, this is not efficient and does not leverage GitLab's native group invitation feature.

Proposed Solution

I am proposing two potential solutions:

1. Extend the existing gitlab_project_members module to include functionality for inviting groups to projects. This would involve adding parameters to specify a group and its access level, and then utilizing the GitLab API's group sharing endpoints.
2. Create a new module, gitlab_project_groups, specifically designed for managing group interactions within projects. This could provide a cleaner separation of concerns, particularly if additional group-specific functionalities are anticipated in the future.

   Both modules would start with basic functionality to invite and uninvite groups to projects without the ability to fetch or modify existing group roles as I have not found a way to do it with the API.

Progress

I have already begun implementing the first option by extending gitlab_project_members to support group invitations. This involves:

• Adding a method to retrieve group IDs based on group names.
• Implementing methods to share and unshare projects with groups using the GitLab API.
• Adjusting the module's argument specifications to handle new parameters related to group management.
