Not possible to disable admin token

[davidfrickert]

Trying to use this chart to replace another old one that i was using but running into issues...

The docs recommend setting adminToken=null to disable admin token but this does not work because because the secrets.yaml template tries to read .Values.adminToken.existingSecret which doesn't work because adminToken is null.

Setting adminToken.value to null also does not work as the chart tries to use the existing secret which i also do not want to use in the _podSec.tpl.
