Find better MySQL image
The stock image `mysql/mysql-server` doesn't seem to be well configured.
We either need to tune the settings or find a better image from a different source.
Boris pointed me to `docksal/mysql` which seems to be much better out of the box.
Ralf pointed to `drud/ddev-dbserver-mysql-8.0`
Once completed, we should also apply those changes to `lakedrops/docker4php`
