    Modify the enrollment status for the logged-in user.

    The request parameter must be a POST request (other methods return 405)
    that specifies course_id and enrollment_action parameters. If course_id or
    enrollment_action is not specified, if course_id is not valid, if
    enrollment_action is something other than "enroll" or "unenroll", if
    enrollment_action is "enroll" and enrollment is closed for the course, or
    if enrollment_action is "unenroll" and the user is not enrolled in the
    course, a 400 error will be returned. If the user is not logged in, 403
    will be returned; it is important that only this case return 403 so the
    front end can redirect the user to a registration or login page when this
    happens. This function should only be called from an AJAX request, so
    the error messages in the responses should never actually be user-visible.

    Args:
        request (`Request`): The Django request object

    Keyword Args:
        check_access (boolean): If True, we check that an accessible course actually
            exists for the given course_key before we enroll the student.
            The default is set to False to avoid breaking legacy code or
            code with non-standard flows (ex. beta tester invitations), but
            for any standard enrollment flow you probably want this to be True.
