Abstraction around ClientTracer which avoids code duplication and adds consistency
in libraries that integrate with brave (Apache Httpclient, Jersey, RestEasy,...).
When extending new libraries with brave support it is advised to use this module.
You'll have to implement you own ClientRequestAdapter and ClientResponseAdapter
and use them with ClientRequestInterceptor and ClientResponseInterceptor.
You can see several examples of this in brave-apache-http-interceptors,
brave-jersey and brave-resteasy-spring.
