Change patched glance client to fit glance-client code change

In Juno Release , "python-glanceclient" component changes code in the
 dir "glanceclient/common" to replace the old http client implementation
 in favor of a new one based on python-request. This leads to glance
driver image sync failed because of lack of http client attributes and
using the method that has never been in new httpclient.
