57ecea2229 Introduce more metrics on concurrency 
Introduce min, average, and standard deviation for the number of
executing mutating and readOnly requests.

Introduce min, max, average, and standard deviation for the number
waiting and number waiting per priority level.

Later:

Revised to use a series of windows

Use three individuals instead of array of powers

Later:

Add coarse queue count metrics, removed windowed avg and stddev

Add metrics for number of queued mutating and readOnly requests,
to complement metrics for number executing.

Later:

Removed windowed average and standard deviation because consumers can
derive such from integrals of consumer's chosen window.

Also replaced "requestKind" Prometheus label with "request_kind".

Later:

Revised to focus on sampling

Make the clock intrinsic to a TimedObserver

... so that the clock can be read while holding the observer's lock;
otherwise, forward progress is not guaranteed (and violations were
observed in testing).

Bug fixes and histogram buckets revision

SetX1 to 1 when queue length limit is zero, beause dividing by zero is nasty.

Remove obsolete argument in gen_test.go.

Add a bucket boundary at 0 for sample-and-water-mark histograms, to
distinguish zeroes from non-zeros.

This includes adding Integrator test.

Simplified test code.

More pervasively used "ctlr" instead of "ctl" as abbreviation for
"controller".

f3fdd5cf9f Add test for windup problem in APF 
The current design for Fair Queueing for Server Requests has a
problem: if the min-max fair result stays different from an even
division for a long time and no queue involved in the imbalance goes
empty then the imbalance keeps accruing in queue virtual state times.

This commit adds a test that demonstrates the problem.

It also has some other tweaks to make other tests less flaky.

Factor the big scenario-testing func into pieces, with supporting
structs.
