Hadoop 2.3 - CM-API - Fred - Code submitted by Paul Webster
   * Fixed an object serialization issue in ApiBaseObject. Objects with inherited
     to_json_dict() methods were not being handled correctly (i.e. ApiRole objects
     with bindings from ApiService objects).
   * Corrected self.instance_of? call in the types.rb/ApiBaseObject _update() method.
   * Added find_role() in api_client so the api user can determine if the role exists
     before creating a role.
   * Added find_role() and create_role() calls to the cluster deployment
     emulation script (create_cluster.rb).
