/**
* Command to forcibly start or stop the agent's {@link AgentMain#getClientCommandSender() client command sender}. This
* allows you to manually tell the sender to start sending commands or stop sending commands even if auto-discovery is
* enabled and wants to do the opposite. Note that if auto-discovery is enabled (this includes server polling as well)
* the sender will probably be set back to its original state when the JON Server's state is auto-detected. This means
* that even if this command is used to start or stop the sender, when auto-discovery detects the server is down it will
* stop the sender again - if the server comes up, it will start the sender again.
