              Get log stream for a service.
              Note: This endpoint works only for services with the ``json-file``
              or ``journald`` logging drivers.
  
              Args:
                  service (str): ID or name of the service
                  details (bool): Show extra details provided to logs.
                      Default: ``False``
                  follow (bool): Keep connection open to read logs as they are
                      sent by the Engine. Default: ``False``
                  stdout (bool): Return logs from ``stdout``. Default: ``False``
                  stderr (bool): Return logs from ``stderr``. Default: ``False``
                  since (int): UNIX timestamp for the logs staring point.
                      Default: 0
                  timestamps (bool): Add timestamps to every log line.
                  tail (string or int): Number of log lines to be returned,
                      counting from the current end of the logs. Specify an
                      integer or ``'all'`` to output all log lines.
                      Default: ``all``
                  is_tty (bool): Whether the service's :py:class:`ContainerSpec`
                      enables the TTY option. If omitted, the method will query
                      the Engine for the information, causing an additional
                      roundtrip.
  
              Returns (generator): Logs for the service.
