feat: additionalIgnoredNamespaces at runtime through helm

[cmwylie19]

Description

This feature:

• Adds additionalIgnoredNamespaces to values.yaml
• Sets additionalIgnoredNamespaces in controller container envs as PEPR_ADDITIONAL_IGNORED_NAMESPACES
• reads PEPR_ADDITIONAL_IGNORED_NAMESPACES env and adds namespaces to ignoredNamespaces
• Does not document PEPR_ADDITIONAL_IGNORED_NAMESPACES as feature is meant to be set through helm chart and not by hand, By hand you should set them in package.json

In action:
package.json

    "alwaysIgnore": {
      "namespaces": ["something"]
    },

values.yaml

additionalIgnoredNamespaces: 
  - 'kube-system'
  - 'kube-public'
  - 'kube-node-lease'
  - 'default'
  - 'pepr'
  - 'pepr-system'
  - 'pepr-test-module'

> helm template .

controllers

            - name: PEPR__ADDITIONAL_IGNORED_NAMESPACES
              value: "kube-system, kube-public, kube-node-lease, default, pepr, pepr-system, pepr-test-module"

webhook configs

    namespaceSelector:
      matchExpressions:
        - key: kubernetes.io/metadata.name
          operator: NotIn
          values:
            - kube-system
            - pepr-system
            - kube-system
            - kube-public
            - kube-node-lease
            - default
            - pepr
            - pepr-system
