= Twitter Message Source
Repeatedly retrieves the direct messages (both sent and received) within the last 30 days, sorted in reverse-chronological order.
The relieved messages are cached (in a `MetadataStore` cache) to prevent duplications.
By default an in-memory `SimpleMetadataStore` is used.
The `twitter.message.source.count` controls the number or returned messages.
The `spring.cloud.stream.poller` properties control the message poll interval.
Must be aligned with used APIs rate limit
