[gnome-boxes/wip/image-import: 4/10] Add support for importing ready-made VMs

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit f470e5ab397e1bde3df65b6e0da2809eea9a0125
Author: Zeeshan Ali (Khattak) <zeeshanak gnome org>

    Add support for importing ready-made VMs
    
    Currently only 'qcow2' and 'raw' images are supported.
    
    Issues/TODO:
    
    * Ensure VM is not launchable by user while import is in progress.
    * Ensure storage is not visible in summary and properties before
      import is ready[1].
    * Report progress of import.
    * Support compress images. This is important for properly supporting
      GNOME ostree images.
    
    [1] This actually make me think if we should import the media during
    wizard's 'preparation' step, keeping in mind that that we intend to
    do downloading of medias in there as well.
