integration tests - Verify Help button redirects to the right URL

[Daniel Korn]

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.

    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
