functional tests should be grouped with other tests (unit and
integration tests). as part of this commit the "common" module
was renamed to just "base", this was done for simplicity.

the post_test_hook.sh file was also copied to the functional module
since it should live there. a separate change to the infra repo
will be made to call the new location, once that is merged we
can remove the old one (a new change will also be posted for that)

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

Partial-Bug: #1596573

Closes-Bug:#1582968

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.

Closes-Bug: #1496337

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
