[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.

**What this PR does / why we need it**:

It removes the deprecated flannel overlay integration in kubelet.
It's completely unnecessary now with CNI which can handle everything smoothly when flannel is running in a daemonset.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #17795, #30589

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.

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.

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.
