25c646cbdd json: never call fsync for stdout or stderr 
We don't need to worry about data loss once the data has been written to an
output stream. Calling fsync unnecessarily has been the reason for performance
issues in the past.

9a867c555c logs: benchmark write performance 
The recent regression https://github.com/kubernetes/kubernetes/issues/107033
shows that we need a way to automatically measure different logging
configurations (structured text, JSON with and without split streams) under
realistic conditions (time stamping, caller identification).

System calls may affect the performance and thus writing into actual files is
useful. A temp dir under /tmp (usually a tmpfs) is used, so the actual IO
bandwidth shouldn't affect the outcome. The "normal" json.Factory code is used
to construct the JSON logger when we have actual files that can be set as
os.Stderr and os.Stdout, thus making this as realistic as possible.

When discarding the output instead of writing it, the focus is more on the rest
of the pipeline and changes there can be investigated more reliably.

The benchmarks automatically gather "log entries per second" and "bytes per
second", which is useful to know when considering requirements like the ones
from https://github.com/kubernetes/kubernetes/issues/107029.

b8501fc10b logs: work around logcheck 
logcheck complains:
Additional arguments to ErrorS should always be Key Value pairs. Please check if there is any key or value missing.

That check is intentional, but not applicable here. The check can be worked
around by calling the functions through variables.

072859c967 logs: create separate test/integration directory 
The benchmark depends on k8s.io/api (for v1.Container). Such a dependency is
not desirable for k8s.io/component-base/logs, even if it's just for
testing. The solution is to create a separate directory where such a dependency
isn't a problem.

The alternative, a separate package with its own go.mod file under
k8s.io/component-base/logs wouldd have been more complicated to maintain (yet
another go.mod file and different whitelisted dependencies).
