Custom Configuration Providers have Dependency Ordering Issues

[grbell-ms]

My team publishes a custom configuration provider that connects to an external service to get config data, which is also updated throughout the lifetime of an application. We want partners to configure the logging, authentication, metrics, etc. when creating our configuration provider, but there is an ordering problem: When creating the config provider, there is no IServiceProvider to get ILogger, Meter, and certificates from.

What's the right way to provide services to a configuration provider?
