NSX|v3: provider networks updates
- Deprecate the "vxlan" type - Add the "geneve" type: with overlay transport zone - Add the "nsx-net" type: attach an existing nsx logical switch (vlan or overlay) to a neutron network. In addition, this patch adds unit tests to all provider networks types. Change-Id: I48a35c913c08ea4afcca64ed2e13db41260b95a3
