Document how to use `kbld` with `kind`?

[Kind](https://kind.sigs.k8s.io) is a popular local development option. Unfortunately, the [default configuration of `kind`](https://kind.sigs.k8s.io/docs/user/quick-start/#loading-an-image-into-your-cluster) requires running `kind load docker-image $IMAGENAME`.

It's hard to extract the built image names to `kind load docker-image`. It would be nice to have something like a `--kind` flag to do this step as long as Kind needs it. (The other option is to [run a local registry](https://kind.sigs.k8s.io/docs/user/local-registry/), but this is harder than needed, especially with additional tools like `pack` or `ko` that may need flags about trusting the registry.)

Start with kbld's CLI options and the linked kind quick-start documentation, especially the `kind load docker-image` workflow. Determine whether the requested outcome is documentation or a new `--kind` flag, then define how built image names are discovered and verify the kind workflow without requiring a local registry.
