Add the ability to filter the Member list in a group or project by role

Background

Today, there is no way to filter the Member list in a project or group by role. See related customer feedback.

Group members page

Project members page

Proposal

Add a role filter to the Members page to allow seeing all members of a certain role within a group or project.

The query and filter component on explorer page has been established. This should be copied to the members page. Currently, the UI supports only Owner on the dropdown. The members page should support:

• Default Roles: Minimal Access, Guest, Reporter, Developer, Maintainer, Owner
• Custom roles

Explorer Page:

• Query:

  • Default Roles: https://gitlab.com/explore?min_access_level=50
  • Custom Roles: TBD

• UI
