Hadoop 2.3 dev
   * Reworked the service.rb module (big delta).
      * Changed the api_client entry points to static method declarations.
      * Patched the service API calls through api_client.rb.
      * Several low level fixes to service object handling (debugging the code with the API test harness).
   * Added find_hosts(), find_services(), find_clusters() to api_client.rb so the API caller can
     determine if resources exist before actually creating the resource.
   * Extended the new test script called create_cluster.rb which deploys a hadoop cluster
     from scratch. This is intended to be a code mock-up of the final chef scripting solution.
   * Extended the api_test_harness.rb script to include the new API entry points that I added.
