    Doc: Improved documentation about LVM overwrite behaviour

    LVM configuration is overwritten on nodes part of the hosts group.
    This documentation explains that behaviour to a deployer, because
    he may not think at first sight that its LVM configuration could
    be overwritten in hosts others than the cinder ones.
