Changes

• Fixed a bug where wildcard hosts were incorrectly added even when a Sidecar resource only specified particular hosts. (Issue #33387)

• Fixed a bug where setting the retryRemoteLocalities on a VirtualService would produce configuration that Envoy would reject. (Issue #33737)

• Improved the meshConfig.defaultConfig.proxyMetadata field to do a deep merge when overridden rather than replacing all values.
