Missing options['object_manager'] in AsResource configuration

[next-sentence]

With yaml format it is possible to set custom object manager per resourse, like this

sylius_resource:
    resources:
        app.book:
            options:
                object_manager: custom
            classes:
                model: App\Entity\Book

but with attributes it is not possible, so you have to duplicate the config

Hi, thanks for opening this issue.

In the "legacy mode", this configuration is useful (So I guess you need this for a Sylius E-commerce resource).
But not with new operations' system.

If your resource is a Doctrine entity, the configured manager will be retrieve like this
https://github.com/Sylius/SyliusResourceBundle/blob/1.12/src/Component/src/Doctrine/Common/State/PersistProcessor.php#L53

If your resource is a not a Doctrine one, you will have to define a processor in your operations to store the data yourself in your persistence system (elastic search, or whatever).

So I will not want to implement this on new AsResource attribute, cause this configuration will be removed at some point.
