Thanks Lei for the great work! This test framework recently helped us
identify bottlenecks and verify improvements for OVN scalability.

As requested by several folks and also mentioned in last week's ovn
meeting, we would like this repo to be hosted publicly under
https://github.com/openvswitch/ so that more people in the community can
contribute and benefit from it. Or it could be a folder under ovs repo,
e.g. ovn/scale-test. The goal is to be able to enable regular regression
test for scalability of ovn, so that we are aware of impact introduced by

Now the tests implemented are the basic ones including Chassis creation,
lswitch and lport creation, address and port-security setting,
lport-chassis binding, etc. Immediate TODOs are:
- Logical routers
- ACLs

Please share your thoughts.
