@jv18creator can we pull FeatureFlags from the generated OpenApi client.. so that we can avoid using configApiSpecs.yaml (which is not checked-in GH repo).

[jv18creator]

@duttarnab I couldn't find endoint to fetch featureFlags from jans_config_api docs.
Perhaps we could fetch AppConfiguration from spec url. I'll start with development.
