Task queue workers as a service

Upload a `package.json` and some JS code to the cloud to spawn auto-scaling workers for a task queue. Somewhat like *now* by zeit.co, but optimized for the auto-scaling task queue use case.

Would be helpful to have it for running shutter.sh and bundle.sh.

### Nice to have features

- Prioritization / rate limiting based on custom conditions / custom logic
- Poll streams - Poll for input data instead of pushing it actively
- Cron jobs
- Provide data storage

### Competitors

- iron.io

### Potential first step

- simple service for scheduling docker tasks & storing logs
- simple service for uploading and managing tasks
- make dockerized job run on swarm stack
