Description

On Mar 15, 2012, Amazon announced a more secure way to sign api requests.

New AWS regions, such as Frankfurt, will not support version 2 which jclouds presently uses:

http://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html

Eventhough some AWS clones like openstack support both versions, not all do. jclouds should support both versions.

This is most important to address for s3 and ec2.
