Tracing Exporters
Tracing Exporters are OpenTelemetry exporter wrappers for Dapr. The actual export implementations should be contributed to the OpenTelemetry repository.
Currently supported exporters are:
- 
Native OpenTelemetry default exporter 
- 
String Export to a string buffer. This is mostly used for testing purposes. 
- 
Zipkin Export to a Zipkin back-end. 
Implementing a new Exporter wrapper
A compliant exporter wrapper needs to implement one interface: Exporter, which has a single method:
type Exporter interface {
	Init(daprID string, hostAddress string, metadata Metadata) error
}
The implementation should configure the exporter according to the settings specified in the metadata.
