Ok so kind of same raw feeling but not same outcome ;).

Let me try to develop what I did today - it is not complete but idea is
here.

1. Mp spec module, mp impl as "usual"
2. Opentracing spec module + opentracing impl in the "impl" module (this is
why i got this issue). I can split in an opentracing-impl module bit having
it all CDI is quite better IMHO and efficient

We can surely refactor it and split it cause the main cdi usage is to fire
a FinishSpan event which hosts a Span and provide a natural extension point
to plug a backend (i intend to just provide a noop and logger impls which
would enable kafka, jdbc, .... through appenders).

Then next step will be to plug config (optionally with a fallback on system
properties) to have a finer config per endpoint (sampling).

Does it sound ok?
