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:

A previous commit replaced the usage of hostname -i with getent hosts
in DNS probe commands (for testing IPv6), which breaks the Windows tests
(getent hosts is a Linux-specific command that looks into the /etc/hosts
file, which, on Windows, is not managed by Kubelet).
This commit addresses this issue by executing getent hosts on IPv6 clusters
and hostname -i on IPv4 clusters (Windows does not support IPv6 at this
moment).
WaitForEndpoint() of the endpoints e2e framework was used in
test/e2e/network/proxy.go only. In addition, the endpoints e2e
framework imported the core of e2e framework only for the function.
So this moves the function into test/e2e/network/proxy.go then we
can remove dependency of core framework from the sub e2e framework.
A number of tests rely on SSH behavior but are not marked with
SkipUnlessSSHKeysPresent(). This means that the tests will run and
hang. This can be confusing for users because they may not know why
the tests failed. Instead, we should be reporting on the known issue
and skipping the test (hence why the helper Skip... function exists).

Quite a few images are only used a few times in a few tests. Thus,
the images are being centralized into the agnhost image, reducing
the number of images that have to be pulled and used.
This PR replaces the usage of the following images with agnhost:
- audit-proxy
- crd-conversion-webhook
- entrypoint-tester
- inclusterclient
- iperf
- porter
- serve-hostname
Current DNS e2e test are only looking for A records, thus all IPv6
tests fail because we should look for AAAA records.
We can ask for both records in the same query, that allows us to
have the same tests for both scenarios.
` dig <name> A <name> AAAA`
In addition, the logic to find the hostname address has to be changed
because the command `hostname -i` fails in an IPv6 environemnt.
However, using `getent hosts $(hostname | ...)` give us the IPv6 adddress
of the current host.
