Adding a perf_tester script which connects to the Client node and
submits queries and waits to match against a response. These files are
defined in the following format:
"""""""""""""""""""""""""""""""""""""""""""""""
__REQUEST__ this is a query
__RESPONSE__
some response data
__RESPONSE__
__DONE__
"""""""""""""""""""""""""""""""""""""""""""""""

If you are not interested in the output from the query, do the
following:

"""""""""""""""""""""""""""""""""""""""""""""""
__REQUEST__ this is a query
__RESPONSE__ __IGNORE__
__DONE__
"""""""""""""""""""""""""""""""""""""""""""""""
