    compute: convert manager to use nova.objects.ImageMeta

    Update the virt driver API so that all methods with an
    'image_meta' parameter take a nova.objects.ImageMeta
    instance instead of a dict.

    NB, this will break out of tree virt drivers until they
    convert their code to use the new object.

this patches change image_meta from dict to object in virt layer

all image reference such as image_meta['properties']['os_version']
cannot be used anymore, we need to figure out a way

    Get image_metadata through glance service

    zvm driver have several attributes that is into image_meta
    object, this means it can't get the value from nova compute
    layer passed down param, so need to get image from glance
    again to guarantee those values can be got.
