Glance will view as image metadata any HTTP header that it receives in a
``PUT`` request where the header key is prefixed with the strings ``x-image-meta-`` and ``x-image-meta-property-``.
If an image was previously reserved, and thus is in the
queued state, then image data can be
added by including it as the request body. If the image
already as data associated with it (e.g. not in the
queued state), then including a request
body will result in a 409
Conflict exception.
On success, the PUT request will
return the image metadata encoded as HTTP headers.
