Currently `image set` uses the new api, where other parts of osc the old
api is used. This deprecates the v2 api in favour of the v1 to maintain
the same commands across osc. However the functionality now remains
there as people could now be using this functionality.

This also adds the --unprotected argument, as in the previous version if
--protected was not supplied it would just make the argument
--unprotected without the users explicit consent.

The patch also fixes the documentation for image set as it was outdated.

We have it for v1, but v2 is the future. There are two differences,
things in v2 do not go into a properties dict, and the actual image
data needs to get uploaded as a second step.

Openstack image create command updates existing image (with same name) by
default. That might be confusing since glance allows create multiple
images with same names and may lead to unwanted image update by image
create command.

Image update code was moved from image create action to image set action.

Closes-Bug: #1461817

This patch includes functional tests for image set and it includes
a change to use the OSC utils.format_dict method to format the
properties.  This will give a more user friendly format to the image
commands and it gives a more consistent testable format to the
output.  Instead of:

{u'a': u'b', u'c': u'd'}

The user will see:

a=b, c=d

Image v2 uses warlock objects rather than the usua Resource objects
so we need to test for those.  This adds a subset of the Image v2
schema that should be enough to test for proper warlock image handling.
