  # datafile - JSON string representing the Optimizely project.
  # logger - Provides a logger instance.
  # error_handler - Provides a handle_error method to handle exceptions.
  # skip_json_validation - Optional boolean param which allows skipping JSON schema
  #                       validation upon object invocation. By default JSON schema validation will be performed.
  # Returns instance of DatafileProjectConfig, nil otherwise.
