Setting up the IAM policy for asynchronous synthesis - Amazon Polly

In order to use the asynchronous synthesis functionality, you will need an IAM policy that allows the following:

use of new Amazon Polly operations
writing to the output S3 bucket
publishing to the status SNS topic [optional]

The following policy grants only the necessary permissions required for asynchronous synthesis and can be attached to the IAM user.
