[RFC] EntityContext: Manage multiple connections

[soullivaneuh]

According to this part of code, it seems you always call the default entity manager for this context.

It would be great to be able to specify which manager to use when we have multiple connections, like this:

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver:   pdo_mysql
                driver_class: AppBundle\DBAL\Driver
                host:     '%database_host%'
                port:     '%database_port%'
                dbname:   '%database_name%'
                user:     '%database_user%'
                password: '%database_password%'
                charset:  UTF8

            powerdns:
                driver:   pdo_mysql
                driver_class: AppBundle\DBAL\Driver
                host:     '%powerdns_host%'
                port:     '%powerdns_port%'
                dbname:   '%powerdns_name%'
                user:     '%powerdns_user%'
                password: '%powerdns_password%'
                charset:  UTF8
        types:
            json: Sonata\Doctrine\Types\JsonType

    orm:
        auto_generate_proxy_classes: '%kernel.debug%'
        default_entity_manager:   default
        entity_managers:
            default:
                connection:           default
                naming_strategy: doctrine.orm.naming_strategy.underscore
                default_repository_class: AppBundle\Repository\DefaultRepository
                mappings:
                    AppBundle: ~
                    FOSUserBundle: ~
                    FOSOAuthServerBundle: ~
            powerdns:
                connection:           powerdns
                naming_strategy: doctrine.orm.naming_strategy.underscore
                default_repository_class: AppBundle\Repository\DefaultRepository
                mappings:
                    PowerDNSBundle: ~

That would be great. Indeed.
