Support for session affinity based on both headers/cookies and weights #1232
Description
we want the ability to route traffic to the application pod based on version cookies during canary deployment. This will make sure during canary deployment requests are routed correctly for both older and newer versions. Based on this thread seems like we need to add this to flagger #1198. We can add this to flagger and wanted to utilize this thread for getting inputs from other folks if they have any specific implementation in their mind or I can come up with the implementation and post the design here
