Do not add new field in fluentd CRI log format.
After https://github.com/kubernetes/kubernetes/pull/55922 is merged, the test `Cluster level logging implemented by Stackdriver should ingest logs` starts to fail in cri-containerd cluster e2e test.
https://k8s-testgrid.appspot.com/sig-node-containerd#e2e-gci
I believe the reason is that the GCP fluentd plugin assumes that there are only `timestamp`, `severity`, `stream` and `log|message|msg` fields in the log entry.
If there is any other fields, GCP fluentd plugin will not try to convert the payload to json, even if the log content is json. The plugin deletes `stream`, `timestamp` and `severity`, then assumes that there is only one field left e13c89a1b6/lib/fluent/plugin/out_google_cloud.rb (L495).
This PR removes the tag field. With this, fluentd GCP plugin should work again.

install ipset in debian-iptables docker image
**What this PR does / why we need it**:
IPVS kube-proxy use ipset doing SNAT and packets filtering. Because IPVS kube-proxy is based on debian-iptables docker image, this PR installs ipset util in the image.

Add cleanup-ipvs flag for kube-proxy
**What this PR does / why we need it**:
There is no way to tell if a given ipvs rule is created by ipvs proxier or not, and some people have complained that iptables/userspace proxier will clean up their ipvs rules when start up - both iptables and userspace proxiers need to clean up legacy proxy rules created by ipvs proxier.
This PR adds a new `--cleanup-ipvs` flag for kube-proxy for the sake of providing users a way to decide if clean up IPVS rules or not when start iptables or userspace proxier.

Fixes#55857

Kubelet flags take precedence over config from files/ConfigMaps
Changes the Kubelet configuration flag precedence order so that flags
take precedence over config from files/ConfigMaps.
See:
https://docs.google.com/document/d/18-MsChpTkrMGCSqAQN9QGgWuuFoK90SznBbwVkfZryo/
Also modifies e2e node test suite to transform all relevant Kubelet flags into
a config file before starting tests when the KubeletConfigFile feature gate is
true, and turns on the KubeletConfigFile gate for all e2e node tests.
This allows the alpha dynamic Kubelet config feature to continue to
work in tests after the precedence change.
fixes#56171
Related: https://github.com/kubernetes/features/issues/281
```release-note
CLI flags passed to the Kubelet now take precedence over Kubelet config files and dynamic Kubelet config. This helps ensure backwards compatible behavior across Kubelet binary updates.
