For ec2 and s3
Until now we had a cloud-aws plugin which is providing 2 disctinct features: * discovery on EC2 * snapshot/restore on S3 This commit splits the plugin by feature so people can use either one or the other or both features. Doc is updated accordingly.
Clean EC2 disco doc Add Azure disco doc Add Google Compute Engine doc Fix Zen doc (add `enabled` in `multicast` parameters list) - Fix #5032.
