Knative Serving release v0.22.3

🚨 Breaking or Notable

1. Fixes for K8s 1.22

Related issue: #11448

Our webhook parser no longer rejects unknown fields in an object's metadata. New fields were introduced in K8s 1.22 which caused Knative's webhook to reject certain operations.

💫 New Features & Changes

• Added an autoscaling annotation to choose a different aggregation algorithm for the autoscaling metrics. This is experimental currently. (#10840, @vagababov)
• Added autocreateClusterDomainClaims flag to network config map. (networking#330, @julz)

🐞 Bug Fixes

• Adds validation that a default max-scale is set if a max-scale-limit is specified in the autoscaler configmap (since otherwise the default max-scale, i.e. 0 = no max, would fail validation as it is above the max-scale-limit). (#10921, @julz)
• Bumped the resource request and limits of the autoscaler to 100m/100Mi, 1000m/1000Mi respectively. (#10865, @markusthoemmes)
• Fixed a regression where the pod bringup time might have a latency of 10s or more even though the container should be up quickly. (#10992, @markusthoemmes)
• Reduced the necessary memory allocations in the activator significantly, especially with disabled tracing. (#11016, #11013, #11009, #11008, @markusthoemmes)
• Fix the incorrect Gateway name format for DomainMapping auto TLS feature for net-istio implmenetation. (net-istio#532, @ZhiminXiang)
