Nova stable/diablo branch unit tests fail when using the ubuntu python-mox package

[Kiall Mac Innes]

The nova unit tests fail when ran outside a virtualenv using the ubuntu oneiric python-mox 0.5.3-1ubuntu4 package, and pass after `pip install mox==0.5.3`

Failed test logs: http://paste.openstack.org/show/3956/

The only difference I can find between the ubuntu package, and the pip package is the backport of this commit into ubuntu's 0.5.3 package: http://code.google.com/p/pymox/source/diff?spec=svn63&r=63&format=side&path=/trunk/mox.py

The failing tests were introduced in: https://review.openstack.org/#q,I7584b527e408c08014f1b6a8abda343f1e2aa3b8,n,z

so the actual issue is that there is a different version of mox 0.5.3 in various places:

https://bugs.launchpad.net/ubuntu/+source/python-mox/+bug/852095

I will create a workaround for this in nova so we can pass in any version.

the difference is that inspect.isroutine returns true in the pypi version of 0.5.3, causing nova/utils.py:to_primitive to short circuit.
