Make the Image v2 image set command meet at the intersection of the v1
image set command and the v2 image create command:
* Add visibility to the deadopts list and remove the option
* Put the options in the same order as v1 image set
* Make the help text match
* Add --properties
* Move the additional options that do not appear in either v1 image set or
v2 image create after --property as they are really pre-defined properties
* Add tests for v2 image set to match v1 and then some
* Put the SetImage class in v2/image.py in alphabetical order
