Add support to download hook target data for stack-level hooks

Stack level hooks will not be provided with invocation payload information, unlike resource level hooks. Instead, Hooks Service will pass in an S3 presigned URL that points to a file that contains the stack-level invocation payload. The base hook handler (before it reaches the customer's handler code), will use that URL to download the data and set it on the target model that is passed to the customer's handler.
