Hi,

This is in relation with the patch at https://review.openstack.org/#/c/55517/ 
which supports use of 'Expect: 100-Continue' header in swift client during a 
PUT request. This will help attain an interim response before actual upload of 
chunks, which will act as a fast fail in case of 401s pertaining to auth-token 
expiration in which case the token will have to be refetched and the request 
retried.

The concern here is that the 'httplib' library currently being used in the 
swift client does not provide support for this header. So the idea is to switch 
to, may be 
httpplus<https://code.google.com/p/httpplus/source/browse/httpplus/__init__.py#212>
 which seems to be handling this header adequately. Thoughts?
