kubectl: Move utility functions to util package
**What this PR does / why we need it**:
`parseFileSource()` and `parseLiteralSource()` are utility functions.
We have a package already for utility functions, `kubectl/util/`.
Move utility functions to `kubectl/util`, capitalize function names to
export from package.

Openapi explain
**What this PR does / why we need it**:
This rewrites `kubectl explain` but using openapi rather than swagger 1.2. Also removes the former code.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#49465, fixes partially #44589, fixes partially #38637
**Special notes for your reviewer**:
FYI @mbohlool
**Release note**:
```release-note
`kubectl explain` now uses openapi rather than swagger 1.2.
```
Major changes:
- Don't generate a patch, instead generate the merged object so it can be used with PUT
- Separate tree parsing logic to collate items in a list from the delete / merge / replace / add logic when merging
- Use openapi for merge strategy metadata so it works with extensions and version skew
- Support multi-field mergekeys when merging lists
- Support replace strategy for maps
- Reduce complexity of generating order when merging lists - keep the locally defined order and append remote only-items
Continue to support:
- Explicitly setting fields to null
- Merging lists of primitives
- Don't randomize ordering when merging lists
TODO:
- Retain keys
- Conflict detection

Add --append-hash flag to kubectl create configmap/secret
**What this PR does / why we need it**:
Specifying this new flag will automatically hash the configmap/secret
contents with sha256 and append the first 40 hex-encoded bits of the
hash to the name of the configmap/secret. This is especially useful for
workflows that generate configmaps/secrets from files (e.g.
--from-file).
See this Google doc for more background:
https://docs.google.com/document/d/1x1fJ3pGRx20ujR-Y89HUAw8glUL8-ygaztLkkmQeCdU/edit
**Release note**:
```release-note
Adds --append-hash flag to kubectl create configmap/secret, which will append a short hash of the configmap/secret contents to the name during creation.
```
Specifying this new flag will automatically hash the configmap/secret
contents with sha256 and append the first 40 hex-encoded bits of the
hash to the name of the configmap/secret. This is especially useful for
workflows that generate configmaps/secrets from files (e.g.

Note that vowels and vowel-like characters in the hash are remapped to
consonants to make it more difficult to accidentally form bad words.

Support exec/attach/portforward in `kubectl proxy`
Use the UpgradeAwareProxy shared code in kubectl proxy. Provide a separate transport for those requests that does not have HTTP/2 enabled. Refactor the code to be a bit cleaner in places and to better separate changes.
Fixes#32026
```release-note
`kubectl proxy` will now correctly handle the `exec`, `attach`, and `portforward` commands. You must pass `--disable-filter` to the command in order to allow these endpoints.

kubectl: deploy generators don't need to impl Generator iface
The `kubectl create deployment` generators do not need to implement the Generator interface, since they are only used as implementations of the StructuredGenerator interface. I was able to delete some tests of their Generator methods as part of this change.
### Considerations for code reviewers
1. Every other StructuredGenerator implementation implements the Generator interface in additional. My change makes the "create deployment" generators a little unusual. I've added a docstring to this effect in `util/factory_client_access.go`.
2. This significantly reduces the maintenance / testing burden for future updates to `kubectl create deployment`.
**Release note**:
```release-note
NONE
```
Requires a separate transport that is guaranteed not to be HTTP/2 for
exec/attach/portforward, because otherwise the Go client attempts to
upgrade us to HTTP/2 first.
Remove kubectl's dependence on pkg/api/helper, as part of
broader effort to isolate kubectl from the rest of k8s.
In this case, the code becomes private to kubectl; nobody else uses it.

**Special notes for your reviewer**:
**Release note**:
```release-note
NONE
```
**What this PR does / why we need it**:
Visibility rules allow dependency control. The rules currently in
place make all targets public, to override the default state of
private. This PR removes public visibility from kubectl code. It
uses specially named pacakge groups to identify "bad" dependencies on
kubectl code for later refactoring or removal.
**Which issue this PR fixes**
First in a series of PRs to address kubernetes/community#598
**Release note**:
```release-note
