Provider specific usage

AWS Route 53

The following IAM policy describes the minimum permissions required to run rancher-letsencrypt using AWS Route 53 for domain authorization.
Replace <HOSTED_ZONE_ID> with the ID of the hosted zone that encloses the domain(s) for which you are going to obtain certificates. You may use a wildcard (*) in place of the ID to make this policy work with all of the hosted zones associated with an AWS account.
