Add configuration option for port

[markusbraje]

Right now there is no possibilty to connect to a non-standard port of a database. It would be quite useful if there was an option for that.

In my current usecase I have a connection to a remote mysql server via ssh-tunnel and I can´t use the default port. because it´s occupied by the local database.

Hi. According to Doctrine DBAL, it is possible to pass a port alongside the host name, see this example: https://www.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url

Does that not work for you?
