Refactor the command source in hexapod and rotator controllers. Based on the test on 2/23, the GUI can issue the command while the CSC is the controller. However, the telemetry shows the CSC is still the commander even though the GUI had issued the command. I thought the CSC should not be the commander at that time (after the GUI issues the command). In addition, it looks like it is better that do not give any restriction to put the CSC as the commander.
