<p>Introduces a delay into a flow or rate limits messages.</p>
<p>The default delay is 5 seconds and rate limit of 1 msg/second, but both can be configured.</p>
<p>When set to rate limit messages, they are spread across the configured time period. It can
also be set to discard any intermediate messages that arrive.</p>
<p>The "topic based fair queue" adds messages to a release queue tagged by their <code>msg.topic</code> property.
At each "tick", derived from the rate, the next "topic" is released.
Any messages arriving on the same topic before release replace those in that position in the queue.
So each "topic" gets a turn - but the most recent value is always the one sent.</p>
<p>The "timed release queue" adds messages to an array based on their <code>msg.topic</code> property.
At each "tick", all the latest messages are released. Any new messages arriving before release will
replace those of the same topic.</p>
