    Fix selection of network volumes
    
    When creating a new VM and selecting a volume from a network-based
    storage pool such as rbd, the volume is not recognized as network-based
    and is treated as a volume from a directory storage pool.
    
    This patch adds a method to check if the volume's path points to a
    network-based volume, then uses the method to avoid actions like
    setting unix file permissions on the volume, which doesn't make
    sense for a network-based volume.
