Updated openstack/openstack
Project: openstack/horizon  d846d029551999a9895401c02786b5fee7f42369

Verify Help button redirects to the right URL

When choosing "Help", in the top bar user drop-down menu,
the browser should redirect to http://docs.openstack.org/
Different distributions might customize the redirection URL,
but the above should be the default.

I added test_dashboard_help_redirection.py, go_to_help_page
method in basepage and the help_url value to horizon.conf
(also forced a change in config.py)

Partially implements blueprint: selenium-integration-testing
Closes-Bug #1350408
