Missing custom headers on CloudFront update

[9b]

Update to the CloudFront Origins is missing a CustomHeader that will cause issues. The key is required, but no data needs to be filled in. You can add the following line to 475 to make it work properly:

'CustomHeaders': {u'Quantity': 0}

On a similar note: 'QueryStringCacheKeys': {'Quantity': 0} is needed in the ForwardedValues in line 493.
