commit 58528cd5a7fbf8248257535055ef03b075e2b3c4

    wic: direct: move UUID generation to PartitionedImage
    
    Moved code that generates partition UUIDs from DirectPlugin to
    PartitionedImage class as it's more logical to have it there.
    This allows the code to be reused by other imager plugins.
    
    Got rid of having yet another list of partitions in PartitionedImage.
    Reused the list passed from DirectPlugin.
