S2ATrustManager now needs to implement X509ExtendedTrustManager because Netty is now doing hostname verification itself if the trust manager is not extended (netty/netty@09e72c4fd8). S2A didn't need to be extended because it received the desired hostname to verify from its constructor, so doesn't need to look it up in SSLSocket/SSLEngine.

NettyClientTransportTest is seeing a different failure now because the server is no longer failing the RPC before sending the response headers (netty/netty@b831454889).
