"""Instrument Consul to trace KV queries.

Only supports tracing for the synchronous client.

``import ddtrace.auto`` will automatically patch your Consul client to make it work.

    from ddtrace import Pin, patch

    client.get("my-key")

    # Use a pin to specify metadata related to this client
