class_docstr: Concrete subclass of BaseDebugWrapperSession implementing a local CLI.
  
  This class has all the methods that a `session.Session` object has, in order
  to support debugging with minimal code changes. Invoking its `run()` method
  will launch the command-line interface (CLI) of tfdbg.
code: def _exit_if_requested_by_user(self):
      if (
          self._run_start_response
          == debugger_cli_common.EXPLICIT_USER_EXIT
      ):
          # Explicit user "exit" command leads to sys.exit(1).
          print(
              "Note: user exited from debugger CLI: Calling sys.exit(1).",
              file=sys.stderr,
          )
          sys.exit(1)
