Bug: Controller fails to init with MySQL

[tetra12]

Error: Failed to set transaction isolation

Related to #15

My Setup:
Remote MySQL: v8.0.35
Controller: v1.25.0

Can connect to the mysql server with: mysql -h mysql -u linstor -p from the linstor controller host

cat /etc/linstor/linstor.toml
[db]
  user = "linstor"
  password = "foo-foo"
  connection_url = "jdbc:mysql://mysql/linstor?createDatabaseIfNotExist=true"
  #connection_url = "jdbc:mysql://mysql:3306/linstor" // doesn't work either

The error message only states that you are missing the JDBC driver for mysql. Please get the corresponding .jar file, and put it into /usr/share/linstor-server/lib/ on the controller.
