Comment 1 for bug 1402928

This seems to have been introduced in https://review.openstack.org/#/c/139649/3/overcloud-without-mergepy.yaml

I'm not sure what the error is here though. If I'm reading the error message correctly, the value "0" is being passed, which is not a string, and which is overriding the default "false". Am i reading the error message wrong?
