More dynamic way of defining topics for KafkaConsumer

[tandev]

Description
In a Symfony-Application using ecotone with Usage of Kafka its possible to
Use the KafkaConsumer-Attribute to define consuming from multiple topics in the following ways:

Using env with Symfony EnvVarProcessor casting to array. Requires excplicit configuration of topics

KAFKA_CONSUMER_ORDER_TOPICS=orders_eu,orders_us

    #[KafkaConsumer(
        endpointId: 'orders',
        topics: '%env(csv:KAFKA_CONSUMER_ORDER_TOPICS)%',
    )]

Using Wildcard. Using with with Tenant-Resolver might make the Resolving fail if there is a topic for a tenant not yet configured.

    #[KafkaConsumer(
        endpointId: 'orders',
        topics: 'orders_.*',
    )]

Using array in code. Requires excplicit configuration of topics

    #[KafkaConsumer(
        endpointId: 'orders',
        topics: ['orders_eu', 'orders_us'],
    )]

For Multi-Tenant-Applications, there might be need for a more dynamic possibility

Example

Using Symfony-Parameters, which could be set in an DI-Extension based on all available tenants

    #[KafkaConsumer(
        endpointId: 'orders',
        topics: '%app.multi_tenancy.kafka.orders.topics%',
    )]

Using Expression:

    #[KafkaConsumer(
        endpointId: 'orders',
        topics: new Expression("reference('config').getOrderTopics()")
    )]

Alternatively it could be an option to allow defining a KafkaConsumer outside of using the Attribute like in EcotoneConfiguration which might reference a MessageConsumer
