[enhancement] Rename the cmd/tf_operator to cmd/tf-operator

[gaocegege]

The new name is more k8s style, and #350 also sets the repo name to tf-operator.

And, the command name in kubeflow should be changed, too.

Hi @gaocegege I would like to work on this issue. Could you please elaborate a little bit since I am just a beginner here.

Hi @AK-ayush

Thank you and I think you just update the package name. But I think we need to make sure that the changes will not break kubeflow. So maybe you need to file a PR to kubeflow, too.

BTW, you could get involved into our community: https://github.com/kubeflow/kubeflow#get-involved. We have an active slack channel :)

@jlewi Could we update the package name now? Or we could wait until we release a version.

This should be fine.

Kubeflow's ksonnet registry uses a specific Docker image so when we update the Docker image we can catch and fix any breakages.

@AK-ayush Then feel free to just update the package name in this repo, and you can file a WIP PR ASAP, the CI test will help you debug 😄
