Extend NetworkPublishing API

[danehans]

Extend the NetworkPublishing API to support the following use cases:

• Set the awsLbBackendProtoAnnotation: tcp annotation only if the provider of LoadBalancerServicePublishingType is AWS.
• Add support to NodePortServicePublishingType to specify: 1) auto (default) or manual port allocation. If manual, provide fields to specify the desired http/https nodePorts (30080 default for http and 30443 default for https).

Support to NodePortServicePublishingType to specify: 1) auto (default) or manual port allocation. If manual, provide fields to specify the desired http/https nodePorts (30080 default for http and 30443 default for https).

This implies the default by choosing option #1 is ports 30080 & 30443. Just want to confirm that's the thought, in my head, auto implies that k8s is specifying the ports which is the default unless you specify the ports (e.g. manual).
