fix PV Recycle issue when running on multi-arch
**What this PR does / why we need it**:
Currently PV Recycle uses image `gcr.io/google_containers/busybox`, which is an amd64 image, not applied for multi-arch , to start pod `"pv-recycler"`. For other non-x86 platforms, like `ppc64le` and `arm64`, the pod cannot get started due to the busybox image.

refactor pd.go for future tests
**What this PR does / why we need it**:
Refactored _test/e2e/storage/pd.go_ so that it will be easier to add new tests, which I plan on doing to address issue 52676
1. Condenses 8 `It` blocks into 3 table driven tests.
2. Adds several `By` descriptions and `Logf` messages.
3. provides more consistent formatting and messages.
**Special notes for your reviewer**:
The diff is large but mostly I've not altered any test. The one semantic change I made was to remove the call to verify a write to a PD when, in fact, nothing had been written yet. This was essentially a no-op since the verify code returned immediately if the passed-in map was empty (which it was since nothing had been written).

Remove dangling shell functions
**What this PR does / why we need it**:
This is clean up for shell functionality that was left over from when something was first added and subsequently removed, but didn't include cleaning up all of the logic they references.
**Special notes for your reviewer**:
I traced back the functions to when they were added and had their references removed, so I thought I'd share that for context:
* `kube::golang::current_platform` was added in 5d33ce46cc, but never ended up being used. My understanding is that this is due to having more or less the same logic available in `kube::golang::host_platform`, which is what's being used.
* `kube::util::gen-analytics` was added in 553f9f822b and had the use of it removed in 902ffd53bc when docs
* `kube::util::analytics-link` was added in 553f9f822b and had the use of it removed in ffcc6cadb0
* `kube::util::get_random_port` was added in 5d08dcf837 and superseded by `kubectl proxy --port=0` in 22b43d8f82
* `kube::util::test_host_port_free` was added in 5d08dcf837 and superseded by `kubectl proxy --port=0` in 22b43d8f82
I should also note that [`kube::golang::unset_platform_envs()`](e8e72a4444/hack/lib/golang.sh (L301-L307)) was introduced in 5d33ce46cc and is currently unused, but was referenced in 9848d6cc8d and subsequently removed in 38690ff7a7. If that's something worth including here, I'd be happy to add that also.

Provide aggregated validation errors for version and kind
Currently the validation checks is done individually for version and
kind group. For example, if user provided yaml file is missing apiVersion
and kind fields, first they will receive error on apiVersion. Once user
update the file and try to recreate, an error on missing kind is displayed.
The behavior is same for wrong types of the fields.
These errors should be aggregated and displayed.
Examples of current validation:
1
test.yaml is missing apiVersion and kind:
$kubectl.sh create -f /home/sahdev/go/src/bugfixes/test.yaml
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: apiVersion not set; if you choose to ignore these errors, turn validation off with --validate=false
2.
test.yaml is fixed for apiVersion but missing kind:
$kubectl.sh create -f /home/sahdev/go/src/bugfixes/test.yaml
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: kind not set; if you choose to ignore these errors, turn validation off with --validate=false
Examples with aggregated validation:
1.
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: [apiVersion not set, kind not set]; if you choose to ignore these errors, turn validation off with --validate=false
2.
error: error validating "/home/sahdev/go/src/bugfixes/testmix.yaml": error validating data: [apiVersion isn't string type, kind not set]; if you choose to ignore these errors, turn validation off with --validate=false
**What this PR does / why we need it**:

Get fallback termination msg from docker when using journald log driver
**What this PR does / why we need it**:
When using the legacy docker container runtime and when a container has `terminationMessagePolicy=FallbackToLogsOnError` and when docker is configured with a log driver other than `json-log` (such as `journald`), the kubelet should not try to get the container's log from the json log file (since it's not there) but should instead ask docker for the logs.

Clean up kublet secret and configmap unit test
**What this PR does / why we need it**:
These changes are clean-up items to fix confusing code encountered while investigating #52043. No actual bugs are fixed here (except, maybe, correcting unit tests that had actual/expected swapped).
A summary of the changes, as listed in the commit:
* Expected value comes before actual value in assert.Equal()
* Use `assert.Equal()` instead of `assert.True()` when possible
* Add a unit test that verifies no-op pod updates to the `secret_manager` and the `configmap_manager`
* Add a clarifying comment about why it's good to seemingly delete a secret on updates.
* Fix (for now, non-buggy) variable shadowing issue
