Recent JDK releases have disabled TLS v1.0 and TLS v1.1 by default
See
- https://java.com/en/jre-jdk-cryptoroadmap.html
- https://bugs.openjdk.java.net/browse/JDK-8202343
This change adds documentation clarifying which TLS versions are
supported on which JDKs (in general terms, rather than specific builds)
and how to change the configuration if necessary.
