Description of problem: Provider mappings were not parameterized, and this is traditionally required for VLAN provider networks. In ODL Boron with new netvirt, this value is required to be set in order to use external networks.
Under review upstream. Will need to be cherry picked to stable/newton
Update: the patch is already cherry-picked to stable/newton - just waiting for it to verify.
Merged upstream
Verified with openstack-tripleo-heat-templates-5.1.0-3.el7ost.noarch
