Moving pod related functions from e2e/framework/pv_util.go to
e2e/framework/pod in order to allow refactoring of pv_util.go into its
own package.

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.
Source code paths during //test/e2e/framework/log:go_default_test in
the Kubernetes CI start with relative paths. To avoid too broad
matching of the regex, those paths that occur in practice are named
explicitly as alternatives to the leading slash.
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.
This test runs a fake Ginkgo suite with various errors and checks how
logger.go respectively ginkgowrapper.go handle this. Right now, the
outcome is sub-optimal:
- some test failures (those that use framework.Failf or
framework.ExpectNoError) are logged immediately, Gomega failures
are not
- framework.ExpectNoError logs just the error, which is often useless
without the additional explanation
- failures that occur after some others are not reported at all;
this can happen in cleanup code and while that code should better
be written so that it contines instead of failing on an assertion,
in practice quite a lot of code fails and when it does, the output
would be useful to have
- the full stack trace is odd and doesn't start with the expected
function name
Example output:
• Failure [0.002 seconds]
