Fixes:
* Don't call LogArgs if log will not be written due low verbosity
* Create separate slice for hijacked to avoid append on main path
* Shorten log message as this log is to common to be verbose

Kubernetes-commit: 303e1c19225149868d735b5c876d8ca9d3e1b5c9
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".
Kubernetes-commit: 57ecea22296797a93b0157169db0ff2e477f58d0
In go1.14, the following change to 'net/url' was made:
"When parsing of a URL fails (for example by Parse or ParseRequestURI),
the resulting Error message will now quote the unparsable URL. This
provides clearer structure and consistency with other parsing errors."
Here we add a new const, 'invalidURLErrFmt' to properly handle the now
quoted string in validation_test.go.

Hello gophers,
Version v0.3.3 of golang.org/x/text fixes a vulnerability in the golang.org/x/text/encoding/unicode package which could lead to the UTF-16 decoder entering an infinite loop, causing the program to crash or run out of memory.
An attacker could provide a single byte to a UTF16 decoder instantiated with UseBOM or ExpectBOM to trigger an infinite loop if the String function on the Decoder is called, or the Decoder is passed to golang.org/x/text/transform.String.
transform.String has also been hardened not to enter an infinite loop if a Transformer keeps returning ErrShortSrc even if atEOF is true.
This issue was first filed as Issue 39491 by GitHub user abacabadabacaba and reported to the security team by Anton Gyllenberg. It is tracked as CVE-2020-14040.
Cheers,
Katie for the Go team
