Added serverless service config #103

Hi @wzedi -- thanks for this effort! Have you investigated the newly announced DynamoDB Global tables? We have started exploring it and it seems like it can manage most of the problems that this library exists to address. Moving forward, we're considering whether we want to deprecate this library in favor of taking advantage of that system. I'd be curious to hear your thoughts and whether global tables sounds like it will satisfy your use cases. |

Hi @rclark, we're using this library specifically as a backup for DynamoDB tables (streams -> versioned S3). We're in Asia Pacific (Sydney) that doesn't currently have On-demand backup and Restore. In this particular case global tables doesn't fit. |

May be better not to specify region or to use a command line option instead

It might be better to move this to the global section so that we can reference them in other parts of the serverless.yml

If the environment variables were global (instead of per-function), we could retrieve this without users having to replace them manually
| - "s3:GetObject" | ||
| - "s3:PutObject" | ||
| - "s3:DeleteObject" | ||
| Resource: "arn:aws:s3:::<YOUR BACKUP BUCKET NAME>/*" |

These could be retrieved as environment variables: ${env:REGION}
