Since the sethostname plugin was moved in plugins.common, there was a bit of Windows specific functionality inside it, the fact that it returns reboot_required in order to set the hostname on Windows. Now this choice is moved to osutils.set_host_name, which will simply return False for non-Windows systems. Change-Id: Ic7774f2c7dd86f3ade82a19520df4301bc9674a7
