A new metadata type `x-envoy-peer-metadata` is being introduced. We don't have a better way to do this at the moment compared to just adding it in `metadata_batch.h`. The GSM Observability plugin uses this metadata to send topology information to peers in the form of serialized and base64 encoded `google::protobuf::Struct`. The individual keys being used inside the struct are subject to change. <!-- If you know who should review your pull request, please assign it to that person, otherwise the pull request would get assigned randomly.
