Recognise CentOS images on AWS Marketplace 

CentOS’ officially-supported AMIs are hosted on the AWS Marketplace.
This adds support for those images, recognising the AMI naming
convention and ensuring the OS metadata is parsed correctly and the
correct SSH login name is used.

There is no change to the default jclouds configuration and the
official CentOS images will not be detected by default. To use these
images, you must alter the ami-query properties to include searching
the “AWS Marketplace”, which has an owner ID of 679593333241. You must
also manually log on to the AWS Marketplace, select your chosen CentOS
image, and “subscribe” to it (you can do this by proceeding as if to
launch an image, but stopping after you have agreed to the subscription
and before launching).
