Description of problem: right now VXLAN is not supported by OVN for regular inter-chassis communication. There is VXLAN support for "vtep" ovsdb schema compliant external switches (aka ramp switches). This RFE is to extend core OVN to support VXLAN for regular in-cluster traffic.

Initial upstream discussion: https://www.mail-archive.com/ovs-discuss@openvswitch.org/msg06771.html
Demo implementation: https://patchwork.ozlabs.org/project/openvswitch/patch/20200320050711.247351-1-ihrachys@redhat.com/

Core OVN work is tracked in bug 1841526. Neutron work is tracked in bug 1881697. This bug is to adjust TripleO to allow to enable VXLAN network type for OVN setups. We should also consider if we want to enable it by default or not.
