Opentracing support

[benmccann]

Parseq tracing is great. I think it would be great to see it adopt the opentracing standard. Opentracing is heavily used by outside of LinkedIn and there is support for much of the tech used by LinkedIn including Couchbase, Play Framework, MongoDB, and Datadog (the latter two are used by Connectifier).

Thanks for the suggestions, we can look into opentracing standard to say how much work is involved as well as extra benefits we can gain compared to existing one.
