Add jobs at runtime

Newly added jobs will change either audit.cfg or repair.cfg,
which are watched by watchdog. Call the right function to add
the job to currently running ones.

Minor typo fixes to cfg files for scripts.

Use utils.load_yaml instead of yaml.load_all. That function
uses safe_load_all, so better security-wise
