Changes

Updated the default value for TRUSTED_GATEWAY_CIDR. Previously this was empty, which caused the XFCC authenticator to reject non-loopback requests.
Added validation warnings when a DestinationRule specifies failover policies but does not provide an outlier detection policy. Previously, istiod was silently ignoring the failover settings.
Fixed an issue causing kube-inject to crash when the pod annotation proxy.istio.io/config is set.
Fixed an issue with a missing service_name in the Telemetry API when configuring a Datadog tracing provider. (Issue #38573)
Fixed an issue where an incorrect schema configuration caused the Istio Operator to go into an error loop. (Issue #40876)
Fixed network port forward issue to support IPv4 and IPv6. (Issue #40605)
