Previously, Packstack did not enable the VPNaaS tab in the Dashboard even if the CONFIG_NEUTRON_VPNAAS parameter was set to 'y'. As a result, the tab for VPNaaS was not shown on the Dashboard.
With this update, a check to see if VPNaaS is enabled has been set up. This check then enables the Dashboard tab in the Puppet manifest. As a result, the VPNaaS tab is now shown on the Dashboard when the service is configured in Packstack.
