    Fixes LP Bug#901534 - Lost properties in upload

    Adds test cases that verify the bug behaviour.

    Adds some logic to the main API images controller
    update() method that does the following:

    * If an image file is being uploaded, do not purge
      existing properties when updating metadata. The idea
      behind this change is that a very common scenario is
      to register an image entry with Glance with some
      properties (like instance_uuid, instance_type, etc) and
      then immediately upload an image (usually snapshots).
      We don't want to mark deleted the originally-registered
      properties during the image upload, which was what was
      happening.

    * Add ability to force Glance NOT to purge properties
      when calling PUT /images/<IMAGE_ID> if the
      X-Glance-Registry-Purge-Props: false
      header is passed.
