This should fix#36110. The current flake rate is 0.5%, so with the
unrealistic assumption of uncorrelated flakes, a single retry will bring
it down to <0.01% flake rate.
Fixes#35850.
GitHub's merging doesn't support .gitattributes-- I verified this with
support. There may be a workaround with line padding or making the bot
do merges on its own, which is beneficial for custom merge conflict
resolution in general.

kubeadm: Fix preflight check failure on node join.
We recently improved this to tolerate existence of things like
/etc/kubernetes/manifests/ as an empty dir, but forgot to do so for the
join pre-flight checks where it is also failing.
Instead ensure only the sub-directories and files we need are available.

mac bash doesn't like |& because mac bash is really old. the formating of wc

Move .gitattributes annotation to the root, so GitHub will respect them.
This should fix the merge conflicts by letting GitHub use the simpler line-by-line algorithm for this file. Having .gitattributes in a sub-directory would work for local merging, but would show conflicts on the web UI.

Expose etcd version.
Ref #20504
This PRs makes use of the following two env variables
- ETCD_IMAGE (if set) allows to use a custom etcd image.
- ETCD_VERSION (if set) allows you to use custom version of etcd. The main purpose of using it may be rollback of etcd v3 API, where we need 3.0.* image, but are rolling back to 2.3.7.
We recently improved this to tolerate existence of things like
/etc/kubernetes/manifests/ as an empty dir, but forgot to do so for the
join pre-flight checks where it is also failing.

Avoid double decoding all client responses
Fixes#35982
The linked issue uncovered that we were always double decoding the response in restclient for get, list, update, create, and patch. That's fairly expensive, most especially for list. This PR refines the behavior of the rest client to avoid double decoding, and does so while minimizing the changes to rest client consumers.
restclient must be able to deal with multiple types of servers. Alter the behavior of restclient.Result#Raw() to not process the body on error, but instead to return the generic error (which still matches the error checking cases in api/error like IsBadRequest). If the caller uses
.Error(), .Into(), or .Get(), try decoding the body as a Status.
For older servers, continue to default apiVersion "v1" when calling restclient.Result#Error(). This was only for 1.1 servers and the extensions group, which we have since fixed.
This removes a double decode of very large objects (like LIST) - we were trying to DecodeInto status, but that ends up decoding the entire result and then throwing it away. This makes the decode behavior specific to the type of action the user wants.
```release-note
The error handling behavior of `pkg/client/restclient.Result` has changed. Calls to `Result.Raw()` will no longer parse the body, although they will still return errors that react to `pkg/api/errors.Is*()` as in previous releases. Callers of `Get()` and `Into()` will continue to receive errors that are parsed from the body if the kind and apiVersion of the body match the `Status` object.
This more closely aligns rest client as a generic RESTful client, while preserving the special Kube API extended error handling for the `Get` and `Into` methods (which most Kube clients use).
```
See issue #33128
We can't rely on the device name provided by Cinder, and thus must perform
detection based on the drive serial number (aka It's cinder ID) on the
kubelet itself.
This patch re-works the cinder volume attacher to ignore the supplied
deviceName, and instead defer to the pre-existing GetDevicePath method to
discover the device path based on it's serial number and /dev/disk/by-id
mapping.
This new behavior is controller by a config option, as falling back
to the cinder value when we can't discover a device would risk devices
not showing up, falling back to cinder's guess, and detecting the wrong
disk as attached.

Making the pod.alpha.kubernetes.io/initialized annotation optional in PetSet pods
**What this PR does / why we need it**: As of now, the absence of the annotation `pod.alpha.kubernetes.io/initialized` in PetSets causes the PetSet controller to effectively "pause". Being a debug hook, users expect that its absence has no effect on the working of a PetSet. This PR inverts the logic so that we let the PetSet controller operate as expected in the absence of the annotation.
Letting the annotation remain alpha seems ok. Renaming it to something more meaningful needs further discussion.

**Special notes for your reviewer**:
**Release note**:
``` release-note
The annotation "pod.alpha.kubernetes.io/initialized" on StatefulSets (formerly PetSets) is now optional and only encouraged for debug use.
