gRPC contains a vulnerability whereby a client can cause a
termination of connection between a HTTP2 proxy and a gRPC server:
a base64 encoding error for `-bin` suffixed headers will result in
a disconnection by the gRPC server, but is typically allowed by
HTTP2 proxies. We recommend upgrading beyond the commit in
