Description
Is your feature request related to a problem? Please describe.
I am trying to create a data prepper pipeline that consumes data from kafka and ingest it into opensearch.
I need to consume from a set of topics whose name is generated dynamically over time, so I don't know it in
advance. I only know that the pattern is always "my-topic-*".
Describe the solution you'd like
I saw that KafkaConsumer supports the subscription to a wildcard topic using patterns,
but it seems data prepper only uses a list of fixed topics.
Is it possible to add the possibility to also consume wildcard topics?
Describe alternatives you've considered (Optional)
I saw that logstash supports this with the topics_pattern key.

Research direction
Start in data-prepper-plugins/kafka-plugins/src/main/java/org/opensearch/dataprepper/plugins/kafka/consumer/KafkaCustomConsumer.java around the fixed-topic subscription at line 321, then compare it with KafkaConsumer's pattern subscription documentation. Done means a pipeline can configure a wildcard topic pattern and consume topics matching it as they are created.
