Heat-proper would have continued working fine with novaclient 2.18.0.
The regression was with raising novaclient exceptions, which is only
required in our unit tests. I saw this break coming and switched to
raising via from_response
https://review.openstack.org/#/c/97977/22/heat/tests/v1_1/fakes.py

Unit tests tend to deal with more internals of client libraries just for
mocking purposes, and there have been multiple breaks in unit tests for
heat and horizon when client libraries make internal changes.

This could be avoided if the client gate jobs run the unit tests for the
projects which consume them.
