Layered configuration?

[MikeGoldsmith]

Currently configuration can only be provided in one of the following ways:

• create instance of HoneycombOptions
• IConfiguration (eg appsettings.json)
• command line args

However, a user cannot mix and match them. Eg set some command line args, some via configuration file, etc. Is this something we want to allow?

I think this is a nice to have and maybe not a requirement for the Beta milestone?

Currently the .NET OpenTelemetry SDK only supports direct code configuration and does not have a defined path for env vars or appsettings. A recent, unreleased, PR was merged to start to introduce env var support as defined in the spec, but this incomplete and could change before it's released.

The current .NET Honeycomb distro supports configuration via command line args, appsettings and command line args but doesn't support layered configuration. We feel this is okay for now as we won't break any base OpenTelemtry SDK configuration options and we can re-assess once the base OpenTelemetry SDK adds env var support.

Moving to Icebox for later consideration.
