By treating the apps in the umbrella as dependencies to be managed and
built by rebar3, we can simplify the maintenance of the release, at
the cost of increased build times: using Mix as before, it could track
changed files better than using rebar. But the complexity and
possibility of discrepancies make it using rebar much more compelling.
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.
