better processing of additional images

[mancdaz]

Not all image tarballs extract to kernel and image files that have the same basename as the tarball. Have changed the logic to figure out the name of the kernel and image files to import into glance rather than just assuming the basename.

mancdaz, you and I did roughly the same thing here.
See my implementation at [1], primarily at [2].

I think it should cover your use case, and additionally supports ramdisks in the .tar.gz and also play .img and .img.gz files.

[mancdaz]

yes yours covers more! One thing I would say - in the image I was testing ( http://uec-images.ubuntu.com/oneiric/current/oneiric-server-cloudimg-amd64.tar.gz), both the vmlinuz-generic and vmlinuz-virtual kernels had been bundled. Your modifications stop on the first match of -vmlinuz*, which happens to be the generic one. Might be worth adding a check to make sure you're always getting -vmlinuz-virtual if it exists, and just -vmlinuz if not.

merges are going through gerrit now guys.

i moved this to reviews.gerrit now.
@mancdaz, the fact that the -generic exists in that tarball is a bug, and it should be fixed now.
