What this PR does / why we need it:

klogr must pass through the verbosity level in case that the underlying backend logger cares about it.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #294

Special notes for your reviewer:

The first commit enhances the output test so that it shows the bug. zapr is needed for that and the test also gets enhanced to support output mapping better.

The second commit then has the actual bug fix and shows that the test now works without a workaround.

Release note:

klogr did not pass the verbosity through to klog, which caused loggers such as zapr to just record v=0.

test: move output test to example, include zapr
bb978b3 
To reproduce the loss of verbosity in
klogr (kubernetes#294) we need a backend which
actually emits the verbosity. zapr does that and also happens to be the logging
implementation used in Kubernetes for JSON, so it makes sense to test with
that.

The expected output mapping may be useful also for testing in Kubernetes,
therefore it gets exported by k8s.io/klog/v2/test.

Because k8s.io/klog/v2 must not depend on zapr, the actual output test gets
moved to the examples. The downside is that "go test ./..." no longer runs it.
One has to remember to enter the "examples" directory. The GitHub action gets
updated to do that.
@pohly
klogr: pass verbosity level through to klog
a58a994 
That wasn't (and still isn't) necessary when klog itself emits the log entry
because it doesn't log the verbosity. But when SetLogger was used to enabled
logging through a backend logger, that logger may care about the verbosity
level.

I was using (cd hack/tools && go test -v -race ./...) earlier, but that failed in Windows. The shell there doesn't seem to support sub-shells.

Is there an absolute path that can be used here?

I fear that the first one will swallow a negative return code from go test.

The simplest solution might be to split up this name: Test into different steps, one for each package. Let me do that...

Functional change seems appropriate, I didn't read the tests too hard.

@pohly
github: split up test steps
7dac793 
Splitting up the tests ensures that each step runs in the right directory
without having to rely on more complex shell scripting. That failures get
reported separately is an added bonus.

The simpler `(cd hack/tools && go test ./...)` wasn't supported by Windows.
