Commit Message

Integrate OpenTracing (#426)

Replace built-in tracing with OpenTracing

Changes:
* internal span reporting completely removed and replaced with OpenTracing
* span context and baggage are propagated via application headers (json only atm, thrift next)
* channel can be configured with `opentracing.Tracer`, otherwise it defaults to `opentracing.GlobalTracer()` (which is no-op by default)
* outbound calls tracing
  * span is started in `(c *Connection) beginCall`
  * if tracer understands "zipkin" format, then the tracing fields are populated in `callReq`
  * the actual span/baggage info is injected in `json/call.go`
  * span is stored in `Response` and finished in a couple of places in `outbound.go`
* inbound requests tracing
  * if tracer understands "zipkin" format, the span is started in `inbound.go` and baggage is added in the encoding handler
  * otherwise span is started in the encoding handler only
  * finished generically in completion callbacks in `inbound.go`
