Functional performance testing harness for 2.0

This is a functional version of the performance testing harness to be used for 2.0. Changes include:

o Updates to Archaius Dependencies
o Removed coupling between standard Blitz4J logging being use to log results
- was nice thanks to asynchronous writes for free
- was complicating the proper setup of appending file loggers in log4j
o Added Amazon S3 based registration of clients
o Removed hack for @Log tag which was causing several issues not to mention improper scope classifiers
o New ResultsLog class that asynchronously logs to a file from a buffer
