Graduate Kustomize cfg read-only commands out of alpha

[KnVerey]

Related to #3953 , which deprecates the rest of the cfg group. The commands in question are:

  cat           [Alpha] Print Resource Config from a local directory.
  count         [Alpha] Count Resources Config from a local directory.
  grep          [Alpha] Search for matching Resources in a directory or from stdin
  tree          [Alpha] Display Resource structure from a directory or stdin.

IMO to keep the read-only commands rather than deprecate them as well, we should:

• Reconsider whether cfg is the prefix we want permanently. @bgrant0607 suggested view, browse or scan as alternatives.
• Make these command support inflating the Kustomization in the targeted directory. In fact, that should probably be the default, since these are kustomize subcommands not, e.g. kubectl plugins.

@KnVerey: This issue is currently awaiting triage.

SIG CLI takes a lead on issue triage for this repo, but any Kubernetes member can accept issues by applying the triage/accepted label.

The triage/accepted label can be added by org members by writing /triage accepted in a comment.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

If we do this, I like scan the most.

Make these command support inflating the Kustomization in the targeted directory. In fact, that should probably be the default, since these are kustomize subcommands not, e.g. kubectl plugins.

So, we would have inflation of the kustomization by default? Would there be an option to use these commands without inflation, say kustomize scan cat . --no-inflate?

I could be convinced otherwise, but yes, that's what I'm thinking

If an on-the-fly build is done first, then this has a dependency on #3979
