text: Title: Add version for Mock Generator
  Body: /kind feature
  
  We should add new instruction to [Makefile](https://github.com/kubeflow/katib/blob/master/Makefile) to run [`mockgen.sh`](https://github.com/kubeflow/katib/blob/master/scripts/mockgen.sh) script with specific mock version.
  
  That will help us to keep files consistent.
