Normalize glanceclient requested service url

Some proxy or gateway softwares, e.g. jumpgate [0], use url-pattern
based approach to match which hanlding logic needs to be triggered for
particular service calling when it received a http(s) call as a
middleman. The change fixed an issue which caused glanceclient send out
the request to a dis-normal url, which contains duplicated "/".

The change removed a wrong and duplicated code snippet from curl logging
function as well.
