Removing the posixpath in python-glanceclient has broken the old target

[Yang Yu]

There is a bug below reported in python-glanceclient to remove the posixpath, but the fix has brought a new regression bug.

https://bugs.launchpad.net/python-glanceclient/+bug/1208618

The code has been changed from

-------------------------------------------
if self.endpoint_path:
                url = '%s/%s' % (self.endpoint_path, url)
            conn_url = posixpath.normpath(url)
----------------------------------------------------
to
-------------------------------------------------------------
             if self.endpoint_path:
                url = urlparse.urljoin(self.endpoint_path, url)
            conn_url = urlparse.urlsplit(url).geturl()

Actually, the urlparse.urljoin() can not work as the code '%s/%s' % (self.endpoint_path, url).
For example, when the self.endpoint_path is '/87823490349243', the url is '/v1/images/details', the output is different for these two line codes. output for '%s/%s' % (self.endpoint_path, url) is /87823490349243/v1/images/details, but output for urlparse.urljoin(self.endpoint_path, url) is only v1/images/details.

It's too bad to introduced this issue. It should be avoided by a unit case.

    not work. The code urlparse.urljoin() can not work as '%s%s' %
    (self.endpoint_path, url).
