MLflow / Kubeflow Tutorial Conflation

[ColmBhandal]

The MLflow tutorial mlflow.rst is today written in a way that also supports the mlflow-kubeflow.rst tutorial. This introduces some issues:

Issue 1

In mlflow-kubeflow.rst, we have this:

Follow the steps in this tutorial to deploy MLflow on your VM: :doc:mlflow

This is not a good UX - sending them off to a separate doc.

Issue 2

In mlflow.rst, we have this:

We're just using kubeflow because often you may want to deploy MLflow along with Kubeflow, and in that case, the model name must be kubeflow. So it's not a bad habit to have.

There are also other references to Kubeflow. This runs the risk of confusing the reader by conflating the pure MLflow tutorial with Kubeflow.
