Change for registration of partitioned images
 - Partitioned images will be in pending_conversion state when registered
 - For each pending_conversion image:
   - ImageConversionManager in ec2 creates a system-owned bucket
   - Worker will upload converted bundles to the created bucket
   - ImageConversionManager calls 'ImportImage' operation of Imaging service
   - DescribeConversionTasks is used by ImportConversionManager to keep track of conversion state
   - When conversion is complete, ImageConversionManager sets the image state to 'available'
 - When an image is deregistered, ImageConversionManager deletes objects and buckets that hold converted image
 - Importimage operation uses entities inherited from the import-instance task record
 - The format of GetImportInstanceReponseType (message from imaging service to worker) is changed to support registration
DownloadCloudCertificate api (which would be used by imaging worker)
Bug fix: set RunManifestLocation for hvm images
Bug fixes in importVolume and importInstance
  - Add the missing volume id to GetInstanceImportTask
  - Reuse downloadManifestUrl when created before (e.g, when the same task is given to more than one workers)
imager and artifact-tree enhancements

- first-cut actual blobstore_delete implementation
- actually doing something in euca-imager fsck
- added support for {download|convert} actions in 'prepare'
- not assuming boot partition is 2nd (or 4th)
- moved known_cmds[] into proper, more global place
- added support for file:/// resources (via file_creator)
