If I want to delete a role, and the role still has members that uses that role, the application refuses to delete the role. At the same time, the application does not tell the requesting user which principals are using the role.

It is thus not easily possible to go through members and delete the roles manually. This is especially true if the roles are used in archived projects.

**Acceptance criteria**

* When a role is still in use, show a DangerConfirmationDialog:
