Optional configmaps and secrets
Allow configmaps and secrets for environment variables and volume sources to be optional
Implements approved proposal c9f881b7bb
Release note:
```release-note
Volumes and environment variables populated from ConfigMap and Secret objects can now tolerate the named source object or specific keys being missing, by adding `optional: true` to the volume or environment variable source specifications.

replace global registry in apimachinery with global registry in k8s.io/kubernetes
We'd like to remove all globals, but our immediate problem is that a shared registry between k8s.io/kubernetes and k8s.io/client-go doesn't work. Since client-go makes a copy, we can actually keep a global registry with other globals in pkg/api for now.

Use privileged containers for host path e2e tests
Test containers need to run as spc_t in order to interact with the host
filesystem under /tmp, as the tests for HostPath are doing. Docker will
transition the container into this domain when running the container as
privileged.

Modify GCI mounter to enable NFSv3
In order to make NFSv3 work, mounter needs to start rpcbind daemon. This
change modify mounter's Dockerfile and mounter script to start the
rpcbind daemon if it is not running on the host.
After this change, need to make push the image and update the sha number in Changelog.

Add more test cases to k8s e2e upgrade tests
**Special notes for your reviewer**:
Added guestbook, secrets, daemonsets, configmaps, jobs to e2e upgrade tests according to the discussions in #35078
Still need to run these test cases in real setup, raised a PR here for initial comments

tests: update memory resource limits
```release-note
NONE
```
On ubuntu, the `RestartNever` test OOMs its cgroup limit fairly
frequently.
This bumps the number up to something suitably large since the test
isn't testing anything related to this anyways.
Fixes#36159
Fix based on https://github.com/kubernetes/kubernetes/issues/36159#issuecomment-258992255
