Front press cron

This adds a cron to `facia-tool` and `admin`.

#### Admin
This pushes all the paths that exist under the `paths` key in `config.json` to a SNS topic every 3 minutes. This SNS topic pushes to a SQS queue.

#### Facia-Tool
This consumes the SQS queue, calling it every 10 seconds. It is quite eager. It takes the path IDs and presses them.

All based around a switch for both pushing paths to the SNS topic and consuming paths from the SQS queue.
In order for the queue not to build up, I am deleting off the queue on press `success` and `failure`.
