This adds a reno note for upgrading to 3.4.0 about zuul-web needing
access to zookeeper now. Also update our components diagram too.

The current stats set a counter zuul.nodepool.<status> but then tries
to set more counters like zuul.nodepool.<status>.label.
This doesn't work because zuul.nodepool.<status> is already a counter
value; it can't also be an intermediate key. Note this *does* work
with the timer values, but that's because statsd is turning the timer
into individual values
(e.g. zuul.nodepool.<status>.<mean|count|std...>) as it flushes each
interval.
Thus we need to rethink these stats. This puts them under a new
intermeidate key "requests" and adds a "total" count; thus
zuul.nodepool.<status> == zuul.nodepool.requests.<status>.total
The other stats, showing requests by-label and by-size will now live
under the zuul.nodepool.requests parent.
While we're here, use a statsd pipeline to send the status update as
it works better when sending lots of stats quickly over UDP. This
isn't handled by the current debug log below; move this into the
test-case framework.
The documentation has been clarified to match the code.
