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".

- Allow client-side to server-side apply upgrade.
Ensure that a user can change management of an object from client-side apply to
server-side apply without conflicts.
- Allow server-side apply to client-side downgrade.
For an object managed with client-side apply, a user may upgrade to
managing the object with server-side apply, then decide to downgrade.
We can support this downgrade by keeping the last-applied-configuration
annotation for client-side apply updated with server-side apply.

This change adds the generic ability for request handlers that run
before WithAudit to set annotations in the audit.Event.Annotations
map.
Note that this change does not use this capability yet. Determining
which handlers should set audit annotations and what keys and values
should be used requires further discussion (this data will become
part of our public API).

This change removes support for basic authn in v1.19 via the
--basic-auth-file flag. This functionality was deprecated in v1.16
in response to ATR-K8S-002: Non-constant time password comparison.
Similar functionality is available via the --token-auth-file flag
for development purposes.

I've also moved the deserialization of the object outside the benchmark
since we're not trying to benchmark the yaml parser.
