endPort not shown in kubectl describe netpol

[huntergregory]

Issue

Recently, our customer was confused if NetworkPolicy implements endPort since kubectl describe does not include endPort field.

From: Azure/azure-container-networking#2313

Question

Should we support port ranges in this field of kubectl describe?

To Port: 80/TCP
