QMYSQL: QT application running in Ubuntu 20.04 wont connect to MySQL 5.7.X servers

The latest MySQL client libraries in Ubuntu 20.04 has by default --ssl-mode=PREFERRED (https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1872541). To connect from 20.04 to a MySQL 5.7.X it is necessary to add --ssl-mode=DISABLED in client applications like mysql and mysqldump.

For QMYSQL such options do not seem to exist thus connecting to 5.7.X MySQL servers is not possible. The problem does not happen when connecting to 8.X servers.
