Description
Enable SNI support for the Java Broker.
We will need a X509ExtendedKeyManager implementation that gets the SNIServerName from the SSL handshakes and then selects the most appropriate certificate alias for the indicated hostname.
I found the following example helpful:
https://github.com/grahamedgecombe/netty-sni-example/blob/master/src/main/java/SniKeyManager.java
https://docs.oracle.com/javase/8/docs/technotes/guides/security/enhancements-8.html
This change requires Java 8, but it is probably possible to retain support for Java 7 using reflection.
It looks to me like the clients (Qpid JMS Client and Legacy) require no changes. They both pass the hostname through to the SSLEngine, so the SNIServerName should already be passed through. Client side support in Java was added at Java 7.
