Provide a mechanism to verify basic networking connectivity before deploying OpenShift in an environment.

Why is this important?

• Networking issues can result in non-obvious deployment failures. It would make debugging a lot easier if we could catch those in isolation before attempting to deploy the rest of the OpenShift components.

Scenarios

1. As an OpenShift deployer, I want to be able to confirm that my host networking is correctly configured before deploying OpenShift.
2. As an OpenShift deployer, I want to have all of the networking tools available to debug problems with host networking.
