Fast DataPath released a new major version of Open vSwitch, which is 3.3.
This version is going to be a new LTS and contains performance improvements
and features required for future releases of OVN.  Since OCP 4.16 is planned
to have a longer support time frame, it should use this version of OVS.
Moving to newer versions of OVS will also gradually allow FDP to drop support
for older streams not used by any layered products.

The change was discussed with FDP, OVS-QE and OpenShift SDN teams.
