No support for Swift Temp URLs in glance_store

[Paul Durivage]

Glance store currently lacks support for Swift storage temporary URLs.

Method parse_uri in glance_store._drivers.http.StoreLocation does not inspect the pieces.query property and utilize this when defining the path attribute, and therefore does not support Swift temporary URLs, which make use of the URL query string. The code begins here: https://github.com/openstack/glance_store/blob/master/glance_store/_drivers/http.py#L80

I can provide a patch shortly.
