  **Improved** request JWT authentication to use the upstream Envoy JWT filter
  instead of the custom Istio Proxy filter. Because the new upstream JWT filter
  capabilities are needed, the feature is gated for the proxies that support
  them. Note that a custom Envoy or Wasm filter that used `istio_authn` dynamic
  metadata key  needs to be updated to use `envoy.filters.http.jwt_authn`
  dynamic metadata key.
