[SPARK-7756] [CORE] Use testing cipher suites common to Oracle and IBM security providers

Add alias names for supported cipher suites to the sample SSL configuration.

The IBM JSSE provider reports its cipher suite with an SSL_ prefix, but accepts TLS_ prefixed suite names as an alias.  However, Jetty filters the requested ciphers based on the provider's reported supported suites, so the TLS_ versions are never passed through to JSSE causing an SSL handshake failure.

Closes #6282 from tellison/SSLFailure and squashes the following commits:
