Fix the connection timeout of the socket for checkChannel()
Need to dig into the actual time until when the connection from felix-client to netio socket lasts. Right now, we have a placeholder time of 5 secs here. After this, the checkChannel() can send another send_data() call to re-establish the connection.
However, something to think about later is that if such a check is needed at all once YARR is integrated into the TDAQ state-machine like environment.
