Remove vpnaas tests from the Neutron API tree

It is important to remove these tests as changes to the
neutron_vpnaas repo can unexpectedly break Neutron,
forcing us to co-gate on vpnaas fix to solve the empasse.

The VPNaaS team should pursue a decoupled testing
strategy, where these types of tests are used to gate
on the vpnaass repo itself. As a temporary measure a
co-gate to neutron would be acceptable (like lbaas)
until neutron-lib takes proper life.
