Ok, I was worried the jinja2 rendering would produce different results
in the plan, in case you had manually edited these files:
~/openstack-tripleo-heat-templates/environments/network-isolation.yaml
~/openstack-tripleo-heat-templates/environments/network-environment.yaml

I'm not quite sure what is wrong, but the fact that you got
'ip_netmask': '' is an indication that some resource might be a Noop
resource or a custom resource without validations? While it should
actually be a port/network resource.

The output of 'openstack stack environment show overcloud' might help.
(NOTE: sanitize the output of that removing sensitive data before
posting it to a public place ...)
