Code Review Request, 8152221 Use try-with-resource in test templates

[Xuelei Fan]

Hi,

Please review this test update for JDK-8152221:

   http://cr.openjdk.java.net/~xuelei/8152221/webrev.00/

The templates for SSL/TLS implementation testing are updated to use
try-with-resource statements.

Thanks,
Xuelei
