Simple daemon to run 'whitelisted' cronjobs from the browser

BGWorker

Run cronjobs/scripts from the webbrowser by calling them through this small daemon.

How is security enforced?

• The daemon runs as a limited user, example systemd-config sets to user script:script
• Because files are directly called thus the execution-flag and shebang are necessary

How does it work?

DevNote: Don't forget to properly urlescape the arguments for file and arg ;)

• HTTP call to /queue/add with ?file=coolscript.sh&args=-write -> returns JSON {id:"uniqueidforscriptbeingrun"}e;
• If you want to keep track, keep polling /queue/status?id=<ID> -> return JSON {status:"PENDING|DONE|ERROR", stdout:"output in stdout and stderr"}

TODO

• Add support for N-workers
• Add support for multiple directories (different rules?)
• Add support for streaming stdout/stderr from script to API?
