Feature Description

A c++ function to set log level of a specific logger under the rclcpp::Logger class.

Implementation Considerations

• the current implementation could be done using the following codes, but it's based on c, not c++:

  if (rcutils_logging_set_logger_level(logger.get_name(), RCUTILS_LOG_SEVERITY_INFO) != 
  RCUTILS_RET_OK)
  {
    RCUTILS_LOG_FATAL("could not set the logger level");
  }

• add a void function that throw an error on fail or add a boolean function that return false on fail under the rclcpp::Logger class.
• (optional) add a more c++ friendly enum to be used to set the log level instead of using the RCUTILS_LOG_SEVERITY enum.
