docs: This function handles all the action: splunk calls this modular input
          without arguments, streams XML describing the inputs to stdin, and waits
          for XML on stdout describing events.
  
          If you set use_single_instance to True on the scheme in get_scheme, it
          will pass all the instances of this input to a single instance of this
          script.
