Support usage with explicit tracer

[bogatuadrian]

Hi,

It would be nice to support an opentracing.Tracer given in constructor instead of using opentracing.StartSpanFromContext() which uses opentracing.GlobalTracer() underneath. This could be an optional feature controlled by an extra flag. I'd be happy to fork the project, add that functionality and make a PR if you would think something like that would be useful.

As an implementation detail, that tracer would be added as an extra field to the generated struct and be used when starting new spans.

Hi @bogatuadrian

Thanks for raising the issue and sorry for a bit delayed response :) Please check new New%sWithTracer constructor. No special flag is needed.

Also please check out generic decorators generator: https://github.com/hexdigest/gowrap
