Python script to delete jobs & nested views in Jenkins-CI

delete-jobs.py

'''
Script to delete jobs and nested views in Jenkins CI including the parent view.
This currently works when you have two-level nested views with jobs under the child view.

Parent view
  - Child view 1
    - Job 1
    - Job 2
  - Child view 2
    - Job 3
    - Job 4

The script will first delete all the jobs in child view, then proceed to delete the child view itself.
Once all child views have been deleted, it will delete the parent view as last step.
