RFR JDK-8211806: TLS 1.3 handshake server name indication is missing on a session resume

[Jamil Nimeh]

Hello all,

This addresses an issue where the client hello in a resumed TLS 1.3 
session lacks the server_name client hello extension.  This can cause 
servers who use this extension field to direct traffic to websites to 
present other certificate chains for other websites than the one the 
client actually desires (and specified in the original client hello 
where the extension is present).
