CloseOptions supports timeout

[robvadai]

Change this line: https://github.com/bakdata/streams-bootstrap/blob/master/src/main/java/com/bakdata/kafka/KafkaStreamsApplication.java#L355

to include an optional timeout value in case the default Long.MAX_VALUE is not satisfactory for someone.

Hi @robvadai, feel free to submit a PR for this. Otherwise we will have a look once we have capacity on our end
