Perfs Test update for scalable stat collection

The commits here introduce an embedded http server using restly that wraps the commandline scripts used to setup a coubase-lite testing environment.  It should be as thin as possible layer between actually running the actual task on the commandline so as to not introduce new errors and possible be integrated into functional tests as defacto way of starting resources.

There is also a new workflow that provides setup/teardown methods via perf/provision.js.  This helps if you already have everything up and running and just want to do some benchmarking.
