Wasn't aware that powering OFF the board would not be a preferred choice
for certain test cases.
Executing python test cases on sandbox or Beaglebone Black with this
power-off feature, did  not
cause me any issues.So,thought this would be a 'good to use' feature in the
python test framework.Hence,this patch.

As recommended , will use this power-off outside the pytest environment.

Thanks ,
Adarsh
