Open Stack

Hi,

I've decided to put up a patch [1] deprecating the aforementioned
features. It's motivated by the fact that there are better ways to do
both:

 * Ingress can be done by another controller or through cloud provider.
 * Namespace isolation can be achieved through network policies.

Both alternative ways are way better tested and there's nobody
maintaining the deprecated features. I'm open to keep them if someone
using them steps up.

With the fact that Kuryr seems to be tied more with Kubernetes releases
than with OpenStack ones and given there will be no objections, we
might start removing the code in the Ussuri timeframe.
