If someone sets `jdk.tls.client.SignatureSchemes` system property they would sure know about it. That property overrides all other signature schemes for both "signature_algorithms" and "signature_algorithms_cert" extensions.

Sounds good. I've created [JDK-8366364](https://bugs.openjdk.org/browse/JDK-8366364) to address this problem. Once it's done we can include signature algorithms in the output.
