Ability to configure some system parameters on the controller
This commit allows the controller to be brought up with the following parameters that can be specified in the config.ini file:
- of.listenPort=6633. TCP port on which the controller is listening (default 6633)
- of.messageResponseTimer=5000. The time (in milliseconds) the controller will wait for a response after sending a Barrier Request or a Statistic Request message (default 2000 msec)
If the paramater is not specified in the config.ini, the controller will use the default value.
