text: Title: Automate Katib Releases
  Body: Currently, to make Katib releases we have to follow this manual process: https://github.com/kubeflow/katib/tree/master/docs/release
  
  We run `make release` command, build and publish the release Docker images locally, and publish Katib SDK version.
  Since we build docker images locally, our release images don't support multi OS arch: https://hub.docker.com/layers/kubeflowkatib/katib-controller/v0.14.0/images/sha256-51ca80d6005010ff08853a5f7231158cb695ea899b623200076cbc01509fc0b5?context=repo.
  
  The release process should be automated. For example, we can utilise GitHub Actions to make Katib releases.
