avoid klog Info calls without verbosity
...
In the following code pattern, the log message will get logged with v=0 in JSON
output although conceptually it has a higher verbosity:
if klog.V(5).Enabled() {
klog.Info("hello world")
}
Having the actual verbosity in the JSON output is relevant, for example for
filtering out only the important info messages. The solution is to use
klog.V(5).Info or something similar.
Whether the outer if is necessary at all depends on how complex the parameters
are. The return value of klog.V can be captured in a variable and be used
multiple times to avoid the overhead for that function call and to avoid
repeating the verbosity level.

Improve queueset sharding and dispatching
...
New anti-windup technique: use the request arrival time as the floor
on the virtual dispatch time. Prevent bound violations where they
might arise rather than fixing up just one queue at dispatch time,
so that the fixed up dispatch times figure into the dispatching choice.
Two tweaks to the shuffle sharding. Take seats of executing requests
into account as well as seats of waiting requests. Do not always
consider the generated hand in the same order.
Rename the queueset methods that do shuffle sharding and finding the
queue to dispatch from, because the old names were confusingly
similar.
Tighten up some request margins.
Name the test cases in TestNoRestraint and TestWindup.
