Support per-connection middleware configuration in doctrine.yaml

[ddegasperi]

Hi,

I'd like to propose a feature for DoctrineBundle that would allow configuring DBAL middlewares per connection directly in the doctrine.yaml configuration file.

This would enable central and consistent management of all connection-related settings in one place — especially useful in applications with multiple DBAL connections.

Currently, middlewares can be configured globally or via attributes/service tags. While this works, supporting configuration at the YAML level per connection would provide a more flexible and declarative approach.

Example:

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver: pdo_pgsql
                url: "%env(DATABASE_URL)%"
                middlewares:
                    - App\Doctrine\CustomMiddleware1
            custom:
                driver: pdo_pgsql
                url: "%env(DATABASE_CUSTOM_URL)%"
                middlewares:
                    - App\Doctrine\CustomMiddleware2

Thanks for your great work on the bundle!

Best regards,
Daniel
