Support for SSL Client Certificate and Key

Is it possible to add support for ssl client certificate and key?

Mysql command equalent:
```
mysql --host=YOUR_SERVER_IP --user=YOUR_USERNAME --password=YOUR_PASSWORD \
      --ssl-ca=/path/to/ca.pem \
      --ssl-cert=/path/to/client-cert.pem \
      --ssl-key=/path/to/client-key.pem
```
