It's fun out of inter dependencies. Nova depends on python-glanceclient;
python-glanceclient depends on warlock>=1.0.1,<2. warlock depends on
jsonschema>=0.7,<2 (warlock 1.0.0). The latest warlock depends on newer
jsonschema release (>=0.7,<3). To fix your issue, you may do one of
following workaround:

1. upgrade warlock to latest (sudo pip install warlock --upgrade)
2. downgrade jsonschema to earlier release v1.3.0 (sudo pip uninstall
jsonschema; sudo pip install jsonschema==1.3.0)
3. install newer python-glanceclient. It depends on newer warlock (sudo pip
install python-glanceclient --upgrade)
