feature: option to add volumes and volumeMounts to minio-operator pod

[yanehi]

Problem

I want to run my minio instance (operator and console) with the readOnlyRootFilesystem: true option. Unfortunately, this isn't possible for the operator pod, since I don't have an option to mount an emptyDir (like I did with the console pod).

So I'm currently getting the following error:

panic: mkdir /tmp/operator: read-only file system

Solution

As with the console pod, I can now optionally use a volume for the operator pod.

values.yaml

  volumes: [ ]
  volumeMounts: [ ]

operator-deployment.yaml

          {{- with .Values.operator.volumeMounts }}
          volumeMounts: {{- toYaml . | nindent 12 }}
          {{- end }}
      {{- with .Values.operator.volumes }}
      volumes: {{- toYaml . | nindent 8 }}
      {{- end }}

@yanehi what type of data will be stored in that emptyDir that you want to mount?. I am just curious and I want to understand why this is needed?. Then we can document it!.
