See comment. This PR is to get the ball rolling, I guess a BC layer must be provided.

I need additional business logic to return the correct DocumentMetadata (the index name is dynamic based on business logic). Besides the context the Operation $operation could be passed as well.

But I'm not sure whether you want to continue this way or remove the DocumentMetadata in favor of extending the ApiPlatform\Metadata\Operation in ApiPlatform\Elasticsearch\Metadata\Operation (as mentioned here by @soyuka)
