Title:
  registering new image from existing s3 location does not respect
  kernel/ramdisk/name

Status in EC2 API:
  New
Status in OpenStack Compute (Nova):
  Confirmed

Bug description:
  $ cloud-publish-image --type kernel --rename my-kernel.img amd64 my.img my-bucket
  aki-0000000f    my-bucket/my-kernel.img.manifest.xml
  $ cloud-publish-image --type ramdisk --rename my-ramdisk.img amd64 my.img my-bucket
  ari-00000010    my-bucket/my-ramdisk.img.manifest.xml
  $ cloud-publish-image --type image --rename my-image-01.img amd64 my.img my-bucket
  ami-00000011    my-bucket/my-image-01.img.manifest.xml
  $ euca-register my-bucket/my-image-01.img.manifest.xml --kernel aki-0000000f --ramdisk ari-00000010 --name my-bucket/my-image-01-with-kenrel-ramdisk.img
  IMAGE   ami-00000012

  $ euca-describe-images ami-00000012
  IMAGE   ami-00000012    my-bucket/my-image-01.img.manifest.xml          available       private         x86_64  machine                 instance-store

  However, if you pass --kernel/--ramdisk the first time you register that s3 location, then it works.
  $ cloud-publish-image --type image --rename my-image-02.img amd64 my.img my-bucket --kernel aki-0000000f --ramdisk ari-00000010
  ami-00000013    my-bucket/my-image-02.img.manifest.xml
  $ euca-describe-images ami-00000013
  IMAGE   ami-00000013    my-bucket/my-image-02.img.manifest.xml          available       private         x86_64  machine aki-0000000f    ari-00000010    instance-store

  The desired behavior is basically to re-register that s3 location but
  with different kernel/ramdisk (or --name) parameters.

  
  Euca-describe-images shows the following:
  $ euca-describe-images | grep my-bucket/
  IMAGE   aki-0000000f    my-bucket/my-kernel.img.manifest.xml               available       private         x86_64  kernel                  instance-store
  IMAGE   ari-00000010    my-bucket/my-ramdisk.img.manifest.xml              available       private         x86_64  ramdisk                 instance-store
  IMAGE   ami-00000011    my-bucket/my-image-01.img.manifest.xml             available       private         x86_64  machine                 instance-store
  IMAGE   ami-00000012    my-bucket/my-image-01.img.manifest.xml             available       private         x86_64  machine                 instance-store
  IMAGE   ami-00000013    my-bucket/my-image-02.img.manifest.xml             available       private         x86_64  machine aki-0000000f    ari-00000010    instance-store
