[axis2] VOTE: move tracer to ws-commons

We currently have the HTTP Tracer (aka tcpmon) in Axis2 and have another
version of it in Axis1.

I suggested this many years ago but was voted down. I'd like to move
this to WS commons because this has NOTHING to do with Axis1 or Axis2
and all it is just a damned useful bit of code. 

Can we please move it to WS commons?

Here's my vote: +1.

Sanjiva.
p.s.: Thanks to Dims for the recent patch which triggered my memory
about wanting to push for this :).
