Check for empty string post trimming
We curl in a retry loop and timeout, trimming stdout to find endpoint names. When curl hits the timeout, stdout is empty, so we insert the empty string into the received set of endpoints.

[Client-gen] Let versioned client use versioned options
i.e., use v1.ListOptions, v1.DeleteOptions when possible.
Remove the extension/v1beta1.ListOptions, because it's exactly the same as v1.ListOptions, and is not referred throughout the code base. After its removal, I register v1.ListOptions during extensions/v1beta1 scheme registration.
First three commits are manual changes.
Fix#27753

Fix kubelet perf data to make it work again for perfdash.
Addresses https://github.com/kubernetes/kubernetes/pull/30333#issuecomment-248791257.
Add the "node" label back to fix kubelet perf dash. At least for now, we still need original perfdash to catch summary api performance regression.

fix apiserver startup check
Startup detection logic was broken. The integration tests weren't checking it because kube integration works differently that openshift integration. :(

kubeadm: refactor config
1) break object into substructures
2) seperate a config object for master and node
3) centralize defaulting and validation
Hacked til it compiled. Have not done 3 yet.
Step one of #33715
Previously, we used the docker config digest (also called "image ID"
by Docker) for the value of the `ImageID` field in the container status.
This was not particularly useful, since the config manifest is not
what's used to identify the image in a registry, which uses the manifest
digest instead. Docker 1.12+ always populates the RepoDigests field
with the manifest digests, and Docker 1.10 and 1.11 populate it when
images are pulled by digest.
This commit changes `ImageID` to point to the the manifest digest when
available, using the prefix `docker-pullable://` (instead of
`docker://`)

CRI: Remove the mount name and port name.
Per discussion on https://github.com/kubernetes/kubernetes/issues/33873.
Currently the mount name is not being used and also involves some
incorrect usage (sometimes it's referencing a mount name, sometimes
it's referecing a volume name), so we decide to remove it from CRI.
The port name is also not used, so remove it as well.

Document selinux considerations in wordpress-mysql example
Fixes#31269.
Even though host path is unsuitable for production environments, it is an option in the wordpress-mysql example. When I followed this example on a RHEL 7.2 system I had issues with selinux.

e2e.go / kops: Add --kops-kube-version
**What this PR does / why we need it**: This adds a flag to override the version we're deploying with kops for e2es. (The kops experience is disconnected from the actual source tree we're running tests from, which is similar to GKE.)

CRI: Implement temporary ImageStats in kuberuntime_manager
For #33048 and #33189.
This PR:
1) Implement a temporary `ImageStats` in kuberuntime_manager.go
2) Add container name label on infra container to make the current summary api logic work with dockershim.
I run the summary api test locally and it passed for me. Notice that the original summary api test is not showing up on CRI testgrid because it was removed yesterday. It will be added back in https://github.com/kubernetes/kubernetes/pull/33779.

Previously, the `InspectImage` method of the Docker interface expected a
"pullable" image ref (name, tag, or manifest digest). If you tried to
inspect an image by its ID (config digest), the inspect would fail to
validate the image against the input identifier. This commit changes
the original method to be named `InspectImageByRef`, and introduces a
new method called `InspectImageByID` which validates that the input
identifier was an image ID.
Per discussion on https://github.com/kubernetes/kubernetes/issues/33873.
Currently the mount name is not being used and also involves some
incorrect usage (sometimes it's referencing a mount name, sometimes

This patch adds the option to set a nodeport when creating a NodePort
service. In case of a port allocation error due to a specified port
being out of the valid range, the error now includes the valid
range. If a `--node-port` value is not specified, it defaults to zero, in
which case the allocator will default to its current behavior of
assigning an available port.
This patch also adds a new helper function in `cmd/util/helpers.go` to
retrieve `Int32` cobra flags.
**Example**
```
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=1
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid
value: 1: provided port is not in the valid range. Valid ports range
from 30000-32767
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
service "mynodeport" created
$ oc describe service mynodeport
