There is no obvious way to use SwiftService with pre-authed token

[Clint Byrum]

In shade, we authenticate once, and then use the same token for multiple services. This is quite useful for something like the rackspace-style image upload, where we need to talk to glance and swift in rapid succession.

But since we need to do segmented uploads for larger images, we need SwiftService. However, it only allows passing in a rigid set of arguments for client.Connection, which dont' include preauthurl and preauthtoken.

IIRC Connection will respect a token passed via the auth_token key in os_options if preauthtoken is not set. Similarly for os_options['object_storage_url'].

Review: https://review.openstack.org/187714
Reason: Seems one can get the connection in a less invasive way with os_options.

Ok, lets call this a documentation bug. It would be better if os_options was a bit better documented. These are in fact mentioned, but very easy to miss unless you know they're there.
