This change allows for the EC2 API call to RegisterImage to support
external URLS provided for the "ImageLocation" parameter:
https://docs.aws.amazon.com/cli/latest/reference/ec2/register-image.html
It enforces that all standards defined there are adhered to
This changes affects RegisterImage from S3 Bucket, requiring
that the "ImageLocation" for it begin with an "s3://" (case-insensitive).
