Option needed to set enabled Cipher suites for SSL connections

When using Java 7 or below, a workaround is needed to specify the cipher suites that can be used to make an SSL connection (as explained in this blog post). However, the MariaDB Connector/J doesn't currently provide this option (e.g. there is no call to the setEnabledCipherSuites method on the SSLSocket in AbstractConnectProtocol).

This task is to add such an option.

Notes

1. Such an option (named "enabledSSLCipherSuites") is provided by the MySQL Connector/J.
2. This issue is described in more detail in the following StackOverflow question:
