Using a private API in jsonschema that has now been removed

[kemitix]

core/jsonutils/renamer.py uses the jsonschema.compat API which is a private API.

The new 4.0.0 and 4.0.1 versions of jsonschema removes that API.

As a temporary workaround, if anybody encounters this issue, you can 'downgrade' your jsonschema version with

python3 -m pip install -U 'jsonschema<4.0'

I just ran into this issue (the cfn command fails saying jsonschema.compat has not been found).

I can confirm @richardhboyd's workaround did make the problem go away for me, but this should definitely be fixed upstream.
