It's a little confusing since we also take the metadata params as
request params - but that is only there to support the HTML UI, and only
done for POST.

The intended way to pass metadata is by using request headers, i.e. for
each key/value pair have a header

        X-Deltacloud-Blobmeta-KEY: VALUE

That's also how they are reported back (as response headers)
