Error getting keystone related informations when running keystone in httpd

[Liyingjun]

1. Need to deploy keystone on apache: http://docs.openstack.org/developer/keystone/apache-httpd.html
2. Update keystone endpoints to, http://192.168.94.129/keystone/main/v2.0 and http://192.168.94.129/keystone/main/v2.0
3. Edit openstack_dashboard/local/local_settings.py, update OPENSTACK_KEYSTONE_URL = "http://%s/keystone/main/v2.0" % OPENSTACK_HOST
4. Visit dashboard,
 * Error on dashboard: `Error: Unable to retrieve project list.`
 * Error in log:
Not Found: Not Found (HTTP 404)
Traceback (most recent call last):
  File "/opt/stack/horizon/openstack_dashboard/dashboards/admin/overview/views.py", line 63, in get_data

    tenants = manager.list(limit, marker)

    resp, body = self.client.get(url)
  File "/opt/stack/python-keystoneclient/keystoneclient/httpclient.py", line 578, in get
    return self._cs_request(url, 'GET', **kwargs)
  File "/opt/stack/python-keystoneclient/keystoneclient/httpclient.py", line 575, in _cs_request

  File "/opt/stack/python-keystoneclient/keystoneclient/httpclient.py", line 554, in request
    resp = super(HTTPClient, self).request(url, method, **kwargs)
  File "/opt/stack/python-keystoneclient/keystoneclient/baseclient.py", line 21, in request
    return self.session.request(url, method, **kwargs)
  File "/opt/stack/python-keystoneclient/keystoneclient/session.py", line 209, in request
    raise exceptions.from_response(resp, method, url)
NotFound: Not Found (HTTP 404)

But using the keystoneclient command line everything works fine..

_get_endpoint_url in openstack_dashboards/api/keystone.py is the source of the problem.
the url is generated by the following codes:

    bits = urlparse.urlparse(url)
    root = "://".join((bits.scheme, bits.netloc))
    url = "%s/v%s" % (root, VERSIONS.active)

this will generate the url like: http://127.0.0.1/v3, but if keystone is running on apache, the right url should be: http://127.0.0.1/keystone/main/v3

    Fix endpoint error when running keystone on apache

    When running keystone in httpd, horizon could not generate the
    right keystone endpoint url. Fixes this issue by retrieving the
    whole path from the service_catalog or OPENSTACK_KEYSTONE_URL
    and generating a new url.
