missingNetworkPolicy should not check ingress/egress rule count

[mblaschke-daimlertruck]

What happened?

the missingNetworkPolicy check is currently enforcing at least one ingress/egress rule.

for plain webservers i don't want to allow any egress rule, also we have jobs which only have egress traffic.

What did you expect to happen?

the check should only over the policyTypes as it's automatically denying traffic if no rules are defined.

How can we reproduce this?

use netpol like:

---
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: webserver
spec:
  podSelector:
    matchLabels:
      app: webserver
  policyTypes:
  - Ingress
  - Egress
  ingress:
  # Ingress
  - from:
    - namespaceSelector:
        matchLabels:
          kubernetes.io/metadata.name: ingress
    ports:
    - protocol: TCP
      port: 8000
