Feature request: support graceful power off and reboot

[chenl]

I read on https://software.intel.com/en-us/articles/intel-active-management-technology-start-here-guide-intel-amt-9 that there are several "new" power state codes. I tried to use these codes with this package to send graceful off and graceful reset (specifically codes 12 - graceful shutdown, and 14 - graceful reset), but instead I get this XML into my std out:

(I apologise in advance for pasting XML)

Tried the same, Doku says:

6. The method returns 'Unknown or Unspecified Error' (2) if the requested PowerState parameter is not supported. In Intel AMT Release 5.0 and earlier releases the method used to return 'NOT_SUPPORTED' (1).
