    Fix instance volume mount script creation

    Now the volume mount script would be created with correct newlines.
    Also, this change contain some additional debugging information, so
    the process of creating and mounting the volume logged to the
    instance /var/log/messages through syslog. Also, this commit contain
    the the workaround for the AuthenticationException because the
    Cirros image starts ssh servece just before the cloud-init and in
    some cases we need to wait when the instance_initial_scenario canges
    the password for the cirros user.
