text: Title: Migrate away from deprecated github.com/hpcloud/tail
  Body: /kind feature
  
  **Describe the solution you'd like**
  
  As https://github.com/hpcloud/tail hasn't been touched for 6 years (it is using Go v1.5.1), and the https://github.com/hpcloud organisation doesn't have any (public) members, we should really stop depending on their code. Multiple forks has been created, but it seems like https://github.com/nxadm/tail is the most popular one, so this could be a potential candidate
  
  **Anything else you would like to add:**
  
  The reason I found this usage of a deprecated package, is that I hit https://github.com/kubeflow/katib/issues/1769 and tried to investigate the issue
