[Suggestion] - Allow smtp configuration via secret / chart about data-center-helm-charts

[bianchi2]

Hi @NandoTheessen while this is not supported out of the box (i.e. a dedicated secret for smtp) I think it should be possible to pass smtp props in setenv.sh and mount the entire file from a pre-created secret. In your values.yaml:

additionalFiles:
  - name: custom-config
    type: configMap
    key: setenv.sh
    mountPath:  /opt/atlassian/jira/bin

This way, you can pre-create the secret (or ConfigMap) with mailserver props in CATALINA_OPTS or JAVA_OPTS and it'll get mounted to the container. In theory it should do the trick (I haven't yet verified it)
