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.

juju: Use k8s.gcr.io url for arm64 ingress image
**What this PR does / why we need it**:
This updates the kubernetes-worker charm to point to k8s.gcr.io for the nginx-ingress-controller-arm64 image. This should have no impact on functionality today, but as I understand it, we're all standardizing on k8s.gcr.io to allow for future changes.

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

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.
