MAX_BACKOFF changed between AWS SDK for Go v1 and v2

[ewbankkit]

The default MAX_BACKOFF value has changed between AWS SDK for Go v1 and v2.
For AWS SDK for Go v1 DefaultRetryerMaxRetryDelay is 300 seconds (5 minutes), whereas for AWS SDK for Go v2 DefaultMaxBackoff is 20 seconds.

This value determines the amount of time between API client request retries and the change in default means the that upgrade from AWS SDK for Go v1 to v2 for services (#32976) is not seamless.
