Use BootID instead of ExternalID to check for new instance
PR #60692 changed the way that ExternalID is reported on GCE. Its value
is no longer the GCE instance ID. It is the instance name. So it
cannot be used to determine VM uniqueness across time. Instead,
upgrade will check that the boot ID changed.
**What this PR does / why we need it**:
Node upgrades stall out because the external ID remains the same across upgrades now.
**Which issue(s) this PR fixes**:
Fixes#62713

Add unit test for configure-helper.sh.
**What this PR does / why we need it**:
Add a framework for unit-testing configure-helper.sh.
configure-helper.sh plays a critical role in initializing clusters both on GCE and GKE. It is currently, over 2K lines of code, yet it has no unit test coverage.
This PR proposes a framework/approach on how to provide test coverage for this component.
Notes:
1. Changes to configure-helper.sh itself were necessary to enable sourcing of this script for the purposes of testing.
2. As POC api_manifest_test.go covers the logic related to the initialization of apiserver when integration with KMS was requested. The hope is that the same approach could be extended to the rest of the script.

provision kubelet config file for GCE instead of deprecated flags
Many Kubelet flags are now deprecated in favor of the versioned config file format. This PR adopts the versioned config file format in our cluster turn-up scripts.
```release-note
cluster/kube-up.sh now provisions a Kubelet config file for GCE via the metadata server. This file is installed by the corresponding GCE init scripts.

cluster/gce/list-resources.sh: also list stackdriver logging sinks
**What this PR does / why we need it**: we seem to be logging stackdriver logging sinks on GCE, likely because we're not keeping track of them. (ref https://github.com/kubernetes/test-infra/issues/7295)
This doesn't fix the leaks, but it'll hopefully help us detect when that happens.

```release-note
NONE

This PR extends the client-side startup scripts to provision a Kubelet
config file instead of legacy flags. This PR also extends the
master/node init scripts to install this config file from the GCE
metadata server, and provide the --config argument to the Kubelet.

Reimplement migrate-if-needed.sh in go
The `migrate-if-needed.sh` script was already partially implemented in go (see the attachlease and rollback sub-dirs), but was still unnecessarily difficult to understand and test. This closely reimplements the original logic but with improved code structure, error handling and testing.
Where possible, go code that was previously executed as separate binaries is now statically linked into a single 'migrate' go cobra CLI app, which is then thinly wrapped by`migrate-if-needed.sh`.
There are numerous additional improvements that need to be made, but will be submitted in future PRs. This PR is focused on achieving parity with the pre-existing functionality and introducing some much needed test coverage, in particular HA cluster upgrade test coverage.
It appears that the `attachlease` and `rollback` go binaries are no longer needed as standalones and so I have consolidated them into the new `migrate` go binary. Other than that, this change aims to be 100% backward compatible.

Add support to ingest log entries to Stackdriver against new "k8s_container" and "k8s_node" resources.
**What this PR does / why we need it**:
**Which issue(s) this PR fixes**
Fluentd 0.14 has some memory leak issues that caused the e2e tests to be flaky. Downgrading to v0.12.
**Special notes for your reviewer**:
We never released any previous version with Fluentd v0.14. Only upgraded it very recently. So this downgrading is not visible to users.
**Release note**:
```release-note
Add support to ingest log entries to Stackdriver against new "k8s_container" and "k8s_node" resources.

Migrating test images to gcr.io/kubernetes-e2e-test-images
**What this PR does / why we need it**:
Currently e2e test images are distributed between 2 different registry locations, k8s.gcr.io and gcr.io/kubernetes-e2e-test-images. This is part of a multi-step initiative to house all the images in gcr.io/kubernetes-e2e-test-images.

Fixes#62131
**Special notes for your reviewer**:
1. I am starting off with migrating images under k8s/test/images/volumes-tester.
2. I did not move ceph and nfs images since they are marked for [deprecation and removal](https://github.com/kubernetes/kubernetes/tree/master/test/images/volumes-tester). Let me know if we want them moved as well.
3. I have made a copy of the images in gcr.io/kubernetes-e2e-test-images so the references are not broken post the PR merge. Will work on removing the images from k8s.gcr.io once this change sticks.
