    doc: Add reminder to have https in api_root

    api_root defaults to http://localhost:8080. In the section about https
    configuration we give directions to set the client side ssl certificate
    and key, but do not mention api_root, which could lead forgetful people
    to mistakes if they don't have the url properly set with https and the
    corresponding encrypted port.
