@mebelousov Help me understand what you are saying, say if
`zeppelin.notebook.cron.enable` (defined in this PR) is set to `true` and
`zeppelin.notebook.cron.folders` is set to `System, Testing` then cron will
only be run on these two folders.
My general opinion about cron is around either user should have permission
or not, not at notebook level.---
