Hi,
This patch extend client to support new drivers collection.
Few examples how it works:
client = DeltaCloud::new('mockuser', 'mockpassword',
'http://localhost:3001/api')
pp client.drivers[1].id => "ec2"
pp client.drivers[1].name => "EC2"
pp client.driver('ec2').providers => ["us-west-1", "ap-southeast-1",
"eu-west-1", "us-east-1"]
pp client.driver('ec2').provider('us-west-1') =>
[{"s3"=>"s3-us-west-1.amazonaws.com"},
{"elb"=>"elasticloadbalancing.us-west-1.amazonaws.com"},
{"ec2"=>"ec2.us-west-1.amazonaws.com"}]
