Turn server-print on by default in kubectl
**What this PR does / why we need it**:

Deployment to stop adding pod-template-hash labels/selector on adoption
**What this PR does / why we need it**: This is a blocker for #55714, because ReplicaSet selector becomes immutable in `apps/v1`. With controller ref, Deployment's ReplicaSets and Pods can avoid fighting with each others without unique label/selector (pod-template-hash), so it's safe to stop adding hash label/selector on adoption.

Fixes#61433
**Special notes for your reviewer**: This is a behavioral change to Deployment controller that will affect all versions of Deployment APIs (`apps/v1`, `extensions/v1beta1`, `apps/v1beta1`, `apps/v1beta2`).
**Release note**:
```release-note
Deployment will stop adding pod-template-hash labels/selector to ReplicaSets and Pods it adopts. Resources created by Deployments are not affected (will still have pod-template-hash labels/selector).

make reapers tolerate 404s on scaling down

Display extended resources in node allocated resources
**What this PR does / why we need it**:
Displays ~~opaque integer~~ [extended] resources in node allocated resources of command `kubectl describe node`. This will give users more info about node ~~OIR~~ [extended resources] consumption.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
This is a partially fix of #44271.
**Special notes for your reviewer**:
This PR
- only displays allocated ~~OIR~~ [extended resources] details of node, it doesn't display ~~OIR~~ [extended resources] requests/limits for each pod because it's hard to organize format. I tried to print ~~OIR~~ [extended resources] requests/limits of pods, but some strings have been eaten when a line is too long (the output has been separated into two lines by terminal). I think it's because a `\t` blank can't be show in two lines.
- ~~uses `OIR-foo` instead of `pod.alpha.kubernetes.io/opaque-int-resource-foo` for short.~~
- doesn't display the percentage of ~~OIR~~ [extended resources] usage because I think the percentage is not so meaningful.
- displays each ~~OIR~~ [extended resources] in single rows to be clear.
UPDATE:
Example with default namespace resource:
```
Non-terminated Pods: (1 in total)
Namespace Name CPU Requests CPU Limits Memory Requests Memory Limits
--------- ---- ------------ ---------- --------------- -------------
default rc-nginx-single-krp84 1 (33%) 1 (33%) 512Mi (6%) 512Mi (6%)

in the array.
