    Fix lock decorator usage for LVM and Generic drivers

    DHSS=False mode of LVM and Generic drivers uses not safe locking
    for NFS helper. So, several instances of same driver may suffer
    from race conditions for modification of NFS config files.

    So, make this lock external (inter-process) and add possibility to
    set up "lock_name", that is useful in case of LVM driver. Also,
    make Generic driver use "instance_id" instead of IP address.
    In those both cases we avoid race conditions.
