feat: dynamodb commit store support (#1410)

This allows users to specify URIs like:

```
s3+ddb://my_bucket/path?ddbTableName=myCommitTable
```

and it will support concurrent writes in S3.

* [x] Add dynamodb integration tests
* [x] Add modifications to get it working in Python sync API
* [x] Added section in documentation describing how to configure.

Closes #534
