Allow running KFP components as Katib Experiments

[fvde]

/kind feature

Describe the solution you'd like
As a user of kubeflow pipelines, there is quite a gap between KFP and Katib. Clean KFP code dictates that I put my operations in isolated components, such as (XGBoost Training). Katib on the other hand requires me to dockerize my training. As a katib and KFP user it would be amazing to submit components to katib for running experiments on.

Anything else you would like to add:

• Fairing could help under the hood, to dockerize the component?
