+ function 'test_logs' allows some types of messages (DBG, TRACE, INFO),
  but the rest of the log messages should rase exceptions

+ function 'check_expected_logs_timeout' periodically calls function
  'check_expected_logs' which watches log messages every second

- functions 'modify_command', 'save_stdout', 'get_attributes_from_output',
  'check_running_protocols' and 'check_protocol_state' were removed
