Crate tracing_honeycomb

This crate provides:

• A tracing layer, TelemetryLayer, that can be used to publish trace data to honeycomb.io
• Utilities for implementing distributed tracing against the honeycomb.io backend

As a tracing layer, TelemetryLayer can be composed with other layers to provide stdout logging, filtering, etc.
