the command ``image set tag <tag> <image>`` is now failing
skip the test so our gate isn't broken.

The tests for image v2 are quite similar to the tests for v1.
The only difference things are:
1. v2 "image set" command only allows to change the disk format
   for a queued image
2. v2 "image show" command output is different from v1

the rest of OSC set commands do not show the resource after it has
been updated. unless the update fails then we report back a failure,
otherwise the user should assume everything went fine.

devstack now defaults to image api v2, but osc does not support
v2 image create. set the functional tests to use v1 for now
to unwedge the gate.

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
