Code Review

This pull request adds support for global image pull secrets by integrating imagePullSecrets into the operator deployment and service account templates, and defining a default empty list in values.yaml. The reviewer provided valuable feedback pointing out potential nil pointer evaluation errors if .Values.global is omitted or null, and suggested wrapping the template blocks in conditional checks to ensure safe navigation.

If .Values.global is omitted or set to null in a custom values file, accessing .Values.global.imagePullSecrets will result in a template rendering error due to a nil pointer evaluation. Wrapping the block in a check for .Values.global prevents this issue.

      {{- if .Values.global }}
      {{- with .Values.global.imagePullSecrets }}
      imagePullSecrets:
        {{- toYaml . | nindent 8 }}
      {{- end }}
      {{- end }}
