Authentication and Authorization Category Split

Purpose

The goal of this issue is to drive discussion and an eventual conclusion on the new category split for Manage::Authentication and Authorization.

Why?

Currently, ~"group::authentication and authorization" only has 1 category: ~"Category:Authentication and Authorization" As the group has grown, there is now a need to break up ~"group::authentication and authorization" into more than one category

Proposal

Category	Description
User Management	Lifecycle management of users, from provisioning to de-provisioning and everything in between
Permissions	Framework for what a user can and can't do within GitLab
System Access	Authentication through all points of GitLab: UI, CLI, API
Credential Management	Lifecycle management of credentials, including tokens, for both users and group owners/admins
