[Maas-devel] Stop the line: tests horribly broken on quantal

I've tracked down the remaining errors.  They are important because the 
uri of the API methods can't be computed and the CLI relies on this.

The problem is an incompatibility between the version of piston in 
quantal and Django 1.4: a method in Django changed its signature and 
piston does not deal well with that.

The issue in piston's bug tracker: 
https://bitbucket.org/jespern/django-piston/issue/218/get_resource_uri_template-broken-in-django

The changeset in Djano which introduces this incompatibility (git show 
fe962149): 
https://github.com/django/django/commit/fe96214939b76d1e7389b1c569d833e96e3a5074

A proper fix means fixing piston itself (a very simple patch could be as 
simple as doing http://paste.ubuntu.com/1218370/ in piston) but we can 
create a monkey patch in MAAS to get us going quickly.
