Configure AWS Signature Authentication for REST

Demonstrates Rest.SetAuthAws, which associates an AuthAws provider so Chilkat signs each request using AWS Signature Version 4. The provider supplies the access key, secret key, region, and service name.

Background. AWS requires each request to be signed with a signature derived from the secret key, region, service, and request contents. Configuring the provider lets Chilkat compute and attach the signature automatically.
