[resteasy] Auto-discovery of jax-rs @Providers

Hello, We are working on OpenTracing jax-rs integration [1]. OpenTracing jax-rs provider [2] can be configured with various settings (tracer instance, span decorators, priority..), but also a default configuration with a parameterless constructor is possible. How should be the provider implemented when we want to allow auto-discovery with a default configuration and also a custom configuration? Currently, the problem is when users want to use a provider with custom configuration a provider with a default configuration is registered too. We want only one to be registered, The default auto-discovered provider should not be used when one is explicitly registered (with a custom configuration). We are thinking about creating a separate artifact with just one class annotated with @Provider to be used when users want to use a default configuration with auto-discovery. The original artifact would be used only for a custom configuration and registration.
