The function is used at e2e framework util module only.
So this moves the function to the module for trying to remove
dependencies to subpackages from core e2e framework.
This cleans up the framework.util.go file and moves various Expect*
functions into their own file for better organization.

This continues the work in
https://github.com/kubernetes/kubernetes/pull/81426 by also moving the
logger_test.go, moving the log helper code from util.go to log.go (a
more logical place, as it is only used there) and updating comments.

ExpectEqual and some of the other wrappers logged the failure twice,
once inside the wrapper itself and once in the failure handler.
Logging the stack backtrace is useful because many assertions still
don't contain an explanation and therefore knowing where they occur is
crucial. Now all failures are logged with a "Full Stack Trace", not
just those with a wrapper. The stack is pruned to skip over wrapper
functions and removes Ginkgo internal functions to keep the stack
trace smaller.
Failures occuring in the wrappers were recorded as occuring in those
wrappers. Now the wrappers are skipped and the caller is recorded
instead.
The full stack trace recorded by Ginkgo 1.10.0 is currently off by one
entry. This needs to be fixed in Ginkgo, then the test can be updated.
Now that namespace deletion is reliable, use the suite tear down
to catch non terminated namespaces and stop waiting within each test
for deletion.
Serial tests that need a clean set of namespaces must use the
appropriate flag to control whether they wait for clean namespaces
on startup.
This is an effort to clean up the framework util.go file so that it
makes more sense and it is more managable.

Remove the "OrDie" from the name (since it doesn't "or die") and add
an extra check that there is at least 1 node available, since many
callers already did that themselves, and many others should have.
PrettyPrintJSON is most used e2emetrics function and that doesn't seem
specific for metrics. The implementation itself is generic, so it is
nice to move it to core framework for avoiding circular dependency.
The `Command` will cause the container process not starting correctly,
so we now use the `Args` to end up running `/agnhost pause` as intended.

Adds a new flag which allows users to specify a regexp
which will effectively whitelist certain taints and
allow the test framework to startup tests despite having
tainted nodes.
Fixes an issue where e2e tests were unable to be run
in tainted environments due to the framework waiting for
all the nodes to be schedulable without any tolerations.
dumpAllNodeInfo() called Nodes().List() internally, but the function
is called from DumpAllNamespaceInfo() only and DumpAllNamespaceInfo()
calls Nodes().List() before calling dumpAllNodeInfo().
So this makes the result of Nodes().List() being passed to
dumpAllNodeInfo() then reduce a call of Nodes().List().
it turns out that the framework.TestContext.IPFamily variable is
not available for the DNS tests if they don't run in the initial
Ginkgo node when running in parallel.
We add a function to the framework to allow us to run command
only once per each Ginkgo node parallel execution.
It also adds a method to detect if the cluster is IPv6.
The use of the framework.TestContext.IPFamily variable guarantees
consistency all over the testing because this variable is only
assigned at the beginning of the testing.
All failures are worth logging immediately, not just unexpected
errors. That helps understand tests that have long-running cleanup
operations with their own logging, because the failure will be visible
inside the test output.
The logging in framework.ExpectNoError also was rather poor, because
it only showed the error, but not the additional information about it.
Tests suites now should use log.Fail as Gomega failure handler instead
of ginkgowrapper.Fail. log.Fail will handle the logging for all
failures before proceeding to record the failure in Ginkgo.
Because logging is always done also after a test failure, additional
failures during cleanup are now visible. Ginkgo itself just ignores
them.
Skips IPv6 tests on Windows.
Skips sysctl tests on Windows.
Skips network policy tests on Windows.
Skips RunAsUser / FSGroup / file permissions related tests, as those are
not supported on Windows.
Skips the test "should preserve source pod IP for traffic thru service cluster IP"
on Windows, as it creates a Pod with HostNetwork=true, which is unsupported.
What works and what doesn't work on Windows has been documented here:
