Pin and fix katib images. (kubeflow#1113)

* The latest images are too old; we should be using the images with tag "master"

* For the 0.2 release we want to pin the images to specific images which
  we tag 0.2.0

* Delete the protoype parameter katibImagTag; image parameters should provide
  the full image reference including the tag. This makes it much easier
  to override certain images and is consistent with other components.

* Create a simple, oneoff script to retag the existing Katib images into
  the Kubeflow image repository

  * We most likely won't ever use this again but its good to leave a paper
    trail.

Related to:
  kubeflow/katib#133 Katib images in 0.2.0-rc.1 are too old
     * Will need to cherry pick this.

  Fix kubeflow/katib#132 Get rid of katibImageTag

  Fix kubeflow/katib#131 Katib prototype needs to pin docker images
