Add MySQL 8 Support

Excuse this request if this is a duplicate feature request.

mysql 8 does not work with virtualmin 6.06-2. I'm waiting for the virtualmin automatic update to include support for mysql 8 so I can continue to use the mysql manager that comes with virtualmin.

Is this feature being worked on for this version of virtualmin?
