Kubernetes e2e suite: [It] [sig-node] Variable Expansion should fail
substituting values in a volume subpath with absolute path [Slow]
[Conformance] test takes 37 seconds to run
We previously skipped this test because Docker did not support mounting
individual files in Containers.
Since then, support for Docker has been removed, and containerd on Windows
supports this feature. We can run this test on Windows.
This changes the text registration so that tags for which the framework has a
dedicated API (features, feature gates, slow, serial, etc.) those APIs are
used.
Arbitrary, custom tags are still left in place for now.
The sysctl tests have to be skipped when the node components are running in UserNS,
because the tests fail due to `open /proc/sys/kernel/shm_rmid_forced: permission denied`
(as expected).
Can be verified with Rootless kind (https://kind.sigs.k8s.io/docs/user/rootless/):
```
dockerd-rootless-setuptool.sh install
: The following steps are added because 'kubetest2 kind --build' does not seem to build e2e.test and ginkgo
make WHAT=test/e2e/e2e.test
make ginkgo
cp -f _output/bin/{e2e.test,ginkgo} _output/dockerized/bin/linux/amd64
kubetest2 kind --build --up --down --test=ginkgo -- \
--use-built-binaries \
--focus-regex='\[NodeConformance\]' \
--skip-regex='\[Environment:NotInUserNS\]'
```
Test with the following host environment:
- kubernetes-sigs/kind@ac28d7fb19 (main)
- kubernetes-sigs/kubetest2@89f09b65e8 (master)
- Docker 24.0.6
- Ubuntu 22.04 amd64, kernel 5.15

The spaces are redundant because Ginkgo will add them itself when concatenating
the different test name components. Upcoming change in the framework will
enforce that there are no such redundant spaces.
Services can expose network applications that are running on
one or more Pods. User need to specify the Port and Protocol of the
network application, and network implementations must forward only
the traffic indicated in the Service, as it may present a security
problem if you allow to forward traffic to a backend if the user
didn't specify it.
