Create the CloudWatch Event via CloudFormation

[cristim]

CloudFormation now supports setting up the event out of the box.

You can have a look at how I did it for one of my projects: https://github.com/cristim/autospotting/blob/master/cloudformation/stacks/AutoSpotting/template.json#L148

Excellent, thank-you! I've updated the CloudFormation stack to include the rule, and updated the documentation to match.
