Is there a way to use the latest available AMI (filtered by owner/AMI name/region etc) to be used as the source image? E.g. "Use the latest Ubuntu 14.04 AMI with an instance type of hvm:ebs-ssd provided by Canonical from the EU-West region"

MSOpenTech currently have this functionality for when building Azure images, and as I look to automate our cloud OS images it would be ideal if the source AMI could be dynamically chosen rather than hard coded into the template/require an env var.

The AWS SDK supports such filtering, although my GO knowledge is a little too limited to provide a suitable PR, sorry!
