As a DevOps engineer, I want to be able to use the Kiali Console to specify what percentage of traffic gets routed to a specific workload (traffic shifting).

Document the Kiali action for creating traffic shifting.

Path to the action in the Kiali console  is   Kiali > Service > Service Details > Create traffic shifting
