Fix image_id in instance resource metadata

Browse Source 
Originally the image property in instance resource metadata is correct
since instance information is fetched from db access.

After switching to nova client api, these information is lost
since the returned data format from nova client is different with db
access result.

Image ref and image url is fixed with this patch while kernel_id and
ramdisk_id should be fixed in nova side.

For bug 1090310
