For 1.23, we removed the kubectl `--dry-run` empty default value (`--dry-run`)
and boolean values (`--dry-run=true` and `--dry-run=false`). This change
required requiring users to specify `--dry-run=client` or `--dry-run=server`
due to a deprecation. This change was made in #105327.
After reconsideration, this change is not worth the churn for users.
It's likely that many users rely on these values for automated and manual use
cases.
This change reverts #105327 and re-introduces the values `--dry-run`,
`--dry-run=true`, and `--dry-run=false`.
The apiserver may be configured to generate the Service
kubernetes.default and its endpoints addresses.
This service is single-stack, hence, the endpoints and the ClusterIP
must have the same IP family.
The tests were asserting that after a NodePort Service was removed,
no new traffic was still reaching the endpoints.
However, the number of tries was so large that another test running
in parallel could create a working Service on that NodePort, making
the test fails.
Use only 10 tries to confirm that the Service stopped working.
The Conformance test "should orphan pods created by rc if delete options say so"
is spawning 80% of the Cluster's Pod Availability (on a 2 node setup, with 30 Pods
capacity each, it spawns 48 pods).
Because of this, tests that are running in parallel with this test has a higher
chance to flake, causing them to timeout because they didn't get to spawn the
necessary Pods within the expected 1 minute time.
Lowering the percentage should reduce the ammount of flakes we see.
Currently when the dockershim socket is used, kubeadm only passes
the --network-plugin=cni to the kubelet and assumes the built-in
dockershim. This is valid for versions <1.24, but with dockershim
and related flags removed the kubelet will fail.
Use preflight.GetKubeletVersion() to find the version of the host
kubelet and if the version is <1.24 assume that it has built-in
dockershim. Newer versions should will be treated as "remote" even
if the socket is for dockershim, for example, provided by cri-dockerd.
Update related unit tests.
Since we removed dockershim we now rely on both flags, which therefore
should not marked experimental any more.

Two simple choices for workqueues do not document that they do not emit
metrics. Using their named variants fixes this, but was undocumented.
