Extend NodePort policy functional testing

[phenixblue]

What would you like to be added:

Since #45 has now been merged we should be able to extend the functional testing for the NodePort policy.

Why is this needed:

We're currently not accurately testing the NodePort policies.

These tests require specific annotations on the target namespace for testing and will require a specifically formatted script that adheres to the pattern specified by the new functional testing framework.

Looking through the Service test manifests, there are some that I'm not 100% sure what they're suppose to be testing, so this may require some additional cleanup once we get started on this.

Specific manifest I'm not sure about:

• test-svc04.yaml

We will also potentially need some additional tests for the various nodePort possibilities with relation of Service config to Namespace labels.

• Label with invalid chars
• Label with various combinations of ranged, single number, etc.
