b2ca0c4c16 Implement finalising state 
Set the canary status to finalising after routing the traffic back to the primary. Run one final loop before scaling the canary to zero so that the canary has a chance to process all inflight requests.

04cbacb6e0 Implement confirm rollout gate and hook 
The confirm-rollout hooks are executed before the pre-rollout hooks. Flagger will halt the canary rollout until the confirm webhook returns HTTP status 200.

ad8d02f701 Use Linkerd metrics when NGINX is the mesh ingress 
Set the metrics provider to Linkerd Prometheus when using NGINX as Linkerd Ingress. This mitigates the lack of canary metrics in the NGINX controller exporter.

88c450e3bd Implement port discovery 
If port discovery is enabled, Flagger scans the deployment pod template and extracts the container ports excluding the port specified in the canary service spec and Istio proxy ports. All the extra ports will be used when generation the ClusterIP services.

6196f69f4d Create New Job when Canary's Interval changes 
- Currently whenever the Canary analysis interval changes, flagger does
not reflect this into canary's job.
- This change will make sure the canary analysis interval got updated whenever
the Canary object's interval changes

29cdd43288 Implement skip analysis 
When skip analysis is enabled, Flagger checks if the canary deployment is healthy and promotes it without analysing it. If an analysis is underway, Flagger cancels it and runs the promotion.
