Moves Hyper-V options to the hyperv section

Fixes Bug: 1140778

Due to the large number of options available in Nova, in order to
achieve better option organization and naming (e.g. avoid the hyperv_*
prefix) and to avoid option name clashes, options specific to the
Hyper-V driver are moved to a section named "hyperv".

Backwards compatibility is mantained by providing the "deprecated_group"
argument in option definitions.

For case consistency the group name as been changed to "hyperv" for options
introduced in Grizzly belonging to the group "HYPERV"
