LOGOUT_URL setting has no effect

[Kristi Nikolla]

Setting LOGOUT_URL in `etc/openstack-dashboard/local_settings.py` has no effect on the URL displayed in the dropdown menu. It still points to `/dashboard/auth/logout/`.

Setting this value is important when using SSO so as to redirect the user to the SSO logout page, and then having that page redirect the user back to `/dashboard/auth/logout/` to unset the session cookies.

I'm currently doing a workaround where I alias that path in the apache configuration, unset the headers, and redirect the user to my SSO logout page.

In our production we are using the SAML2 SSO login.

It is very important to be able to correctly logout from the SAML Identity Provider (same case for OpenID) when the user logs out of Horizon.

Can you please fix this issue.

    Forwards LOGOUT_URL to templates.

    Uses the openstack context preprocessor to pass
    the LOGOUT_URL from settings to templates and
    changes the 'Sign out' menu entry to redirect to it
    instead of the logout view directly.
