R&D on Opentracing integration

The more we move to a distributed architecture
the more the need to trace request across the full Nuxeo stack and services increases.

Opentracing is an open standard for distributed tracing, it is not tied to a specific reporting (tracer) implementation.
For instance it could work with open source solutions:

• jaeger
• zipkin
  as well as commercial products
• lightstep
• datadog APM

Most of our thrid part services are covered:

• mongodb
• jdbc
• elasticsearch
• kafka
• also javascript, apache or nginx

We could also add a trace id in the logs so we can be able to trace completly a user request.

A poc should be started to estimate the integration effort.
