    Fix readme for multi-node setup

    The readme currently states that a compute node in a multi-node setup
    requires the glance-api service to be enabled. But actually
    the glance-api service is only required on the controller node where
    glance-registry is running.
    Running the glance-api service on a node without glance-registry will
    even lead to a failure of glance-api, as the glance cache directory
    will not be created without enabling glance-registry.
