"No api version was specified..."

Running openstack esi node network list fails with:

No API version was specified or the requested operation was not supported by the client's negotiated API version 1.72. Supported version range is: 1.1 to 1.72

We can work around this by setting OS_BAREMETAL_API_VERSION=1.72 in the environment, but:

We should be able set baremetal_api_version in clouds.yaml, but this doesn't appear to work.
The error message suggests that the client negotiated version 1.72 and that failed, which doesn't make any sense.
This only impacts the openstack esi ... command; openstack baremetal commands work without error.

E.g.:
