Looking at this example

- name: portal-config
     emptyDir:
        medium: Memory 
- name: portal-config-input
     configMap:
        name: {{ include "common.fullname" . }}-portal

AAI components sometimes attempt to mount two volumes  XXXX and XXXX-input

Since AAF is not enabled on Service Mesh, one of these volumes is not needed and result in an error.

Change is meant to condition the use of XXXX-input volumes only when AAF is enabled, and use the configmap pour XXXX instead. The previous snippet would then look like this:

- name: portal-config
 {{- if .Values.global.aafEnabled }}
     emptyDir:
        medium: Memory 
- name: portal-config-input
{{- end }}
     configMap:
        name: {{ include "common.fullname" . }}-portal

Change applies to graphadamin, sparky-be and modelloader.

EDIT: In addition, babel is not working and a fix is applied on a later review
