Load local image in local-deploy (#192)

* Load local image in local-deploy

* Remove a trivial comment

* Add kind-load-image target

* Fix 'kind load image-archive' command

It doesn't support input from STDIN

* Change imagePullPolicy to IfNotPresent

When deployed on KinD, the image is pre-pushed to KinD from the local registry.
When deployed on OCP, OCP will pull the image from quay.io.
