Knowing how long a URL has spent in the queues is very useful and a good addition to knowing how long the actual fetching took. This could be used for instance to throttle the emissions of URLs from a particular backend, similar to #504. These also reflect the robots wait directives - as well as the actual waiting time for the queue.

This should also be provided as metrics.
