XD-1814 Acceptance Tests for Labels and Taps

* Includes Transform fixture as well.
* Improvements to Result File Validator.
** The file validator now checks to see if the file is present and loops
   for a period of time with one second pauses if not present.
   Before we always waited pausetime *2000 (millis).
** Runtimes were about 17 min with the latest checks.  Now they are
   running around 12 min.
* testStreamTapTwoProcessors Uses labels vs. module index.
* Delimiter now spelled correctly
* Thread.currentThread().interrupt() is now in the catch block for the thread.sleep
* Removed code for index that was no longer relevant.
