The PowerInterface methods set_power_state() and reboot() were enhanced
to take a 'timeout' parameter [1].
In the Queens release [2] , the conductor assumes that all PowerInterfaces
can support this timeout parameter. This patch changes the PowerInterfaces
so that they accept a 'timeout' parameter for reboot() and set_power_state().
The PowerInterfaces log a warning if the parameter is specified when it isn't
supported.
