    Reorganize role assignment tests for system users

    The GET /v3/role_assignments API is a read-only API, making the
    behavior for all system users the same. They should all be able to
    list and filter role assignments for the entire deployment.

    This commit moves the existing system reader tests into a common class
    that can be reused by other test classes for system members and system
    administrators.

    Subsequent patches will:

      - add test coverage for system members
      - add test coverage for system admins
      - add functionality for domain readers
      - add functionality for domain members
      - add functionality for domain admins
      - add functionality for project readers
      - add functionality for project members
      - add functionality for project admins
      - remove the obsolete policies from policy.v3cloudsample.json
