exception handling in kafka streams instrumentation

[jorgheymans]

Currently all tracing variants of the stream components throw any exception encountered in the delegate upwards. If the tracing stream component is the top-level stream component (we can assume this will be the case a lot) then such exception likely kills the stream.

A pattern to avoid this is to wrap the Tracing stream component with another one and catch the exception there. Maybe there are better solutions (Stream.setUncaughtExceptionHandler ?) that can avoid this.
