[openstack-dev] [ironic] SOFT_REBOOT powers off/on the server

A soft reboot should allow the server to shut down gracefully.  A reset 
wouldn't do that, at least as I understand it.  A reset would be more 
appropriate for a hard reboot, although I see Dmitry had a couple of 
other concerns with implementing it as a reset on the review.
