This makes horizon work with recent versions of anyjson. Note that
there's another jsonutils change in openstack-common, but it requires
timeutils (which adds a dependency on the iso8601 module), so I skipped
it for now.
Changes from openstack-common:

Add 'filedecoder' method to the jsonutils wrapper module.
Fixes bug #1017765
After version 3.3.2, the anyjson library will throw a KeyError if
filedecoder isn't present. The filedecoder is just like the decoder
except it takes a file instead of a string, like json.load() instead
of json.loads().
