Need Feedback on Tracing PR

[Sandeep Paliwal]

Hi All,

I had been working on adding OpenTracing support to OpenWhsik.
Here is PR for that -
https://github.com/apache/incubator-openwhisk/pull/2282
Markus has been helping me out with the review.

It will be great to get more feedback on this.

thanks,
Sandeep Paliwal

Note this is the native implementation all-in-one I built. 
I am working on the implementation with the subprocess connected with a pipe, 
and I hope it will give similar performances...
