%<em>ssl_name</em> at the begining of the connection string means to use
a ssl client certificate for authentication.
This will use a CA certificate located at
<code>$INSTANCEHOME/etc/zmysqlda/[%ssl_name]-ca.pem</code>, a client certificate
at <code>$INSTANCEHOME/etc/zmysqlda/[%ssl_name]-cert.pem</code> with a key
at <code>$INSTANCEHOME/etc/zmysqlda/[%ssl_name]-key.pem</code>.
This will also verify that the connection is using ssl and cause an error
when an encrypted connection can not be established.
