Switched to using cirros images rather than ubuntu cloud images, as
they are smaller, and thus better for testing. They should also go
through the zuul reverse proxy.
Update env variables to work with the tweaks to snapstack.

Tweaked tox.ini to invoke snapstack, and added test_snapstack.py to
tests dir.
Also added glance.sh to glance/tests, as part of the plan to move
those scripts from snap-test to the individual snaps.

Classic confinement allows the snap to behave like a traditionally
packaged application with full access to the system, and enables the
use of traditional directories such as /etc and /var/log.
We will continue to store all of the snap's files in $SNAP* directories.
This enables the snap to cleanup after itself if it is removed. However,
traditional directory locations are symlinked to their corresponding
$SNAP* directories.
For example, glance configs are installed in $SNAP_COMMON/etc/glance
which has a symlink at /etc/glance.
The glance apps then use the traditional directories when running
commands and services.
