Set trace information to new transaction

[xitaocrazy (Daniel de Souza Martins)]

Hi @GregKalapos,

Thanks for your answer, and for your help, I will pull master and do a local build to test this constructor. It is all I need, retrieve and set de trace context in my transactions. I already did a local build to test the distributed tracing, now I will test this new feature that lets me manually works with trace context.
