General MR

Summary

Adds support to cluster-auditor for custom network policies via values yaml.

This depends on big-bang/bigbang!4184 (merged) for a documentation reference

Relevant logs/screenshots

Given these overrides:

clusterAuditor:
  enabled: true
  git:
    repo: https://repo1.dso.mil/big-bang/product/packages/cluster-auditor.git
    tag: null
    path: chart
    branch: "95_additional_network_policies"
  values:
    networkPolicies:
      enabled: true
      additionalPolicies:
      - name: this-is-a-cluster-auditor-job-test-test
        spec:
          podSelector: {}
          policyTypes:
          - Egress
          egress:
          - to:
            - ipBlock:
                cidr: 172.20.0.0/12
      - name: this-is-a-zwei-cluster-auditor-job-test-test
        spec:
          podSelector: {}
          policyTypes:
          - Ingress
          ingress:
          - from:
            - ipBlock:
                cidr: 172.20.0.0/12

.. We get network policies (new ones at the bottom):
