how to use ovn-scale-test to test raft cluster database

[winsopc]

Hi Team,

I studied some slides from Aliasgar, very helpful for me to run standalone testing.
For now, I want use 3 KVM vms as cluster, and use several BMs for test farms.
Could someone help me how to modify the json files in the deployment/task to finish the scale test?

Regards,
