Bug fixes

Fix Galley Helm charts so that the validatingwebhookconfiguration object can now deployed to a namespace other than istio-system (Issue 13625).
Additional Helm chart fixes for anti-affinity support: fix gatewaypodAntiAffinityRequiredDuringScheduling and podAntiAffinityLabelSelector match expressions and fix the default value for podAntiAffinityLabelSelector (Issue 13892).
Make Pilot handle a condition where Envoy continues to request routes for a deleted gateway while listeners are still draining (Issue 13739).

If access logs are enabled, passthrough listener requests will be logged.
Make Pilot tolerate unknown JSON fields to make it easier to rollback to older versions during upgrade.
Add support for fallback secrets to SDS which Envoy can use instead of waiting indefinitely for late or non-existent secrets during startup (Issue 13853).
