Enable Neutron VPNaaS API CI tests

VPNaaS API CI test is not enabled since the current api test code has some
issues, however our team has fixed it in this patch:
https://review.openstack.org/#/c/335838/, and also vpnaas project need this
API tests, so here create a new API CI job to enable vpnaas api CI tests.
