authn configs are checked independently per-auth provider,
this was to make authn providers more plugable.
in order to make environment variable overrides work for authn,
we need to have a unified view of the config layout,
no matter from root level, or partially checking per-provider
config independently, i.e. we try to use the same config envelop.
