    installed-media: Allow bypassing format check
    
    In certain cases (e.g the cloning code that will be added in a following
    patch), the media will already be in qcow2 format so there is no need to
    check for format of disk image. Moreoever, currently our disk images
    lack the file extension so our own code breaks on detecting it's type as
    we rely on file extensions for detection.
