Migrate kubelet and linked code from clientset_generated to client-go

Ran a script in the kubernetes repo to migrate kubelet and linked code from clientset_generated package imports to client-go imports.

**NOTE:** There are also some manual changes that were made in order to accommodate some
differences between clientset_generated and client-go. The manual changes are isolated into a
single commit titled "Manual changes."

```sh
#! /bin/bash

for file in $(find . \( -name "clientset_generated" -o -name "informers_generated" \) -prune -o -type f -name "*.go"); do

  if [[ -d $file ]]; then
    continue
  fi

  if [[ $file == "./cmd/libs/go2idl/informer-gen/main.go" ]]; then
    continue
  fi
