AWS Credentials should not be required

[quiddle]

Hard-coding AWS credentials is the least recommended option:

1. Loaded from IAM roles for Amazon EC2 (if running on EC2),
2. Loaded from the shared credentials file (~/.aws/credentials),
3. Loaded from environment variables,
4. Loaded from a JSON file on disk,
5. Hardcoded in your application

By requiring the AWS Credentials, it prevents using these other methods.

The ember-cli-deploy-s3 plugin recently fixed this with pull request 39.

~~I'm also fairly certain that if region is specified in a ~/.aws/config file, it will get picked up by the AWS SDK as well. Looking into that for sure.~~
