Implement custom help command for kubectl

```release-note
* kubectl help now provides "Did you mean this?" suggestions for typo/invalid command names.
```

Custom implementation of help command allows to print `Did you mean this?` with
suggestions, which is missed in embed help command from github.com/spf13/cobra

Also, it can be extended with different search features. At this patch, help
command searches query in short descriptions of commands in case of mismatch
with commands names.

fixes #25234
