Consider supporting remote controller reboots (power cycles)

[gavanderhoorn]

Not sure this should be added.

It's possible, but depending on how it's implemented would leave the controller vulnerable to unplanned/unexpected reboots if/when someone figures out the URI of the resource we'd use from dominh.

It would be convenient though when using dominh to remotely configure a controller (and some setting / system variable requires a reboot to take effect).
