Previously we refused to emit 'autoConvert_*' functions if any field was not
convertible. The way around this was to write manual Conversion functions, but
to do so safely you must handle every fields. Huge opportunity for errors.
This PR cleans up the filtering such that it only operates on types that should
be converted (remove a lot of code) and tracks when fields are skipped. In
that case, it emits an 'autoConvert' function but not a public 'Convert'
function. If there is no manual function, the compile will fail.
This also means that manual conversion functions can call autoConvert functions
and then "patch up" what they need.

Improvements on OpenAPI spec generation
- Generating models using go2idl library (no reflection anymore)
- Remove dependencies on go-restful/swagger
- Generate one swagger.json file for each web-service
- Bugfix: fixed a bug in trie implementation
Reference: #13414
**Release note**:
```release-note
Generate separate OpenAPI spec for each API GroupVersion on /<Group>/<Version>/swagger.json
```
There's been enough people broken by not committing generated code, that we
should undo that until we have a proper client that is `go get` compatible.
This is temporary.
This mostly takes the previously checked in files and removes them, and moves
the generation to be on-demand instead of manual. Manually verified no change
in generated output.
This drives conversion generation from file tags like:
// +conversion-gen=k8s.io/my/internal/version
.. rather than hardcoded lists of packages.
The only net change in generated code can be explained as correct. Previously
it didn't know that conversion was available.
This is the last piece of Clayton's #26179 to be implemented with file tags.
All diffs are accounted for. Followup will use this to streamline some
packages.
Also add some V(5) debugging - it was helpful in diagnosing various issues, it
may be helpful again.
This drives most of the logic of deep-copy generation from tags like:
// +deepcopy-gen=package
..rather than hardcoded lists of packages. This will make it possible to
subsequently generate code ONLY for packages that need it *right now*, rather
than all of them always.
Also remove pkgs that really do not need deep-copies (no symbols used
anywhere).
In bringing back Clayton's PR piece-by-piece this was almost as easy to
implement as his version, and is much more like what I think we should be
doing.
Specifically, any time which defines a .DeepCopy() method will have that method
called preferentially. Otherwise we generate our own functions for
deep-copying. This affected exactly one type - resource.Quantity. In applying
this heuristic, several places in the generated code were simplified.
To achieve this I had to convert types.Type.Methods from a slice to a map,
which seems correct anyway (to do by-name lookups).
Make unversioned.ListMeta implement List. Update all the *List types so they implement GetListMeta.
This helps avoid using reflection to get list information.
Remove all unnecessary boilerplate, move the interfaces to the right
places, and add a test that verifies that objects implement one, the
other, but never both.
