[bitnami/kafka] Adding "external" PV controllers like vSphere for OpenShift

[iamigui]

Name and Version

bitnami/kafka:latest

What is the problem this feature will solve?

The problem of generating PVC based on vmdk volumes for vSphere (as an example)

What is the feature you are proposing to solve the problem?

By adding this line in broker/controller.persistence

vsphereVolume: {}

 vsphereVolume: {}
    ## fsType: ext4
    ## volumePath: "[vsanDatastore] volumes/kafka-dev.vmdk"

and also configuring the statefulset to write it.

  volumeClaimTemplates:
    {{- if and .Values.broker.persistence.enabled (not .Values.broker.persistence.existingClaim) }}
    - apiVersion: v1
      kind: PersistentVolumeClaim
      metadata:
        name: data
        {{- if .Values.broker.persistence.annotations }}
        annotations: {{- include "common.tplvalues.render" (dict "value" .Values.broker.persistence.annotations "context" $) | nindent 10 }}
        {{- end }}
        {{- if .Values.broker.persistence.labels }}
        labels: {{- include "common.tplvalues.render" (dict "value" .Values.broker.persistence.labels "context" $) | nindent 10 }}
        {{- end }}
      spec:
        accessModes:
        {{- range .Values.broker.persistence.accessModes }}
          - {{ . | quote }}
        {{- end }}
        resources:
          requests:
            storage: {{ .Values.broker.persistence.size | quote }}
        {{- include "common.storage.class" (dict "persistence" .Values.broker.persistence "global" .Values.global) | nindent 8 }}
        {{- if .Values.broker.persistence.selector }}
        selector: {{- include "common.tplvalues.render" (dict "value" .Values.broker.persistence.selector "context" $) | nindent 10 }}
        {{- end -}}
        {{- if .Values.broker.persistence.vsphereVolume.enabled }}
        vsphereVolume: {{- include "common.tplvalues.render" (dict "value" .Values.broker.persistence.vsphereVolume "context" $) | nindent 10 }}
        {{- end }}

What alternatives have you considered?

It will also be needed configuration for the rest of the external storage class providers, like Azure, AWS, etc.

It is referred in this documentation:
