Convert HPA controller to support HPA v2 mechanics
This PR converts the HPA controller to support the mechanics from HPA v2.
The HPA controller continues to make use of the HPA v1 client, but utilizes
the conversion logic to work with autoscaling/v2alpha1 objects internally.
It is the follow-up PR to #36033 and part of kubernetes/features#117.
**Release note**:
```release-note
NONE
```
There was a bug in the HPA v1 conversion logic that would occur when
a custom metric and a metric that was encoded in v1 as
targetCPUUtilizationPercentage were used at the same time. In this
case, the custom metric could overwrite the CPU metric, or vice versa.
This fixes that bug, and ensures that the fuzzer tests round-tripping
with multiple metrics.

move pkg/fields to apimachinery
Purely mechanical move of `pkg/fields` to apimachinery.
Discussed with @lavalamp on slack. Moving this an `labels` to apimachinery.
@liggitt any concerns? I think the idea of field selection should become generic and this ends up shared between client and server, so this is a more logical location.
Recent changes to support multiple methods for discovery meant that
"kubeadm init" no longer was sufficient and users would need to add
"--discovery token://" to achieve the same results.
Instead lets assume discovery if the user does not specify anything else
to maintain parity and the brevity of our original instructions.
This implements the proposal in:
docs/proposals/secret-configmap-downwarapi-file-mode.md
Fixes: #28317.
The mounttest image is updated so it returns the permissions of the linked file
and not the symlink itself.
