This issue is caused by python-openstackclient from pypi.
----
python-openstackclient (1.5.0)
----
This version of openstackclient does not support type options in cli.

After setting 'export DEVSTACK_PROJECT_FROM_GIT=python-openstackclient' in CI, a much newer version of python-openstackclient which supports type options in cli is installed and the issue is gone.
-----
python-openstackclient version in git is 1.5.1.dev135
