Mock has a method called assert_called_once_with to check that a mock
was called and the arguments it took were as expected. Mock does not
have a method called assert_called_once and calling it just creates a
mock bound to that name. This means that not only is nothing tested
when assert_called_once is used, the tests also don't warn about this.
This commit attempts to address this in two ways:
- all occurrences of assert_called_once are replaced with a real
assertion.
- the hacking check that nova uses to guard against this has been
copied to cinder's local hacking checks.
Fixing the assert_called_once issues also highlighted other mistakes
in certain tests which were addressed to make the tests pass.
Due to the nature of mock, this issue is also possible if a method is
misspelt or just mistakenly used and so the hacking check is only
addressing one very specific case. That said, it does appear to be a
common mistake and so is worth singling out.

The Choose Your Own Adventure README for Cinder
You have come across a storage service for an open cloud computing service. It has identified itself as "Cinder." It was abstracted from the Nova project.
To monitor it from a distance: follow @openstack on twitter.
To tame it for use in your own cloud: read http://docs.openstack.org
To study its anatomy: read http://cinder.openstack.org
To dissect it in detail: visit http://github.com/openstack/cinder
To taunt it with its weaknesses: use http://bugs.launchpad.net/cinder
To watch it: http://jenkins.openstack.org
To hack at it: read HACKING.rst
