GCP Kubernetes Engine Clusters Have Network Policy Disabled

This policy identifies Kubernetes Engine Clusters which have disabled Network policy. A network policy defines how groups of pods are allowed to communicate with each other and other network endpoints. By enabling network policy in a namespace for a pod, it will reject any connections that are not allowed by the network policy.
