Automatically setting password modification time to the current time leads to
it changing every time the chart is rendered. Ironically, this is a problem
when Argo CD manages itself using this chart ;-)
The argocd application expects that the label 'app.kubernetes.io/part-of' is set to 'argocd' otherwise the configmap or secret is rejected, and the argocd-dex-server, argocd-server, and argocd-application-controller fail to start.
