Announcing AWS DMS Serverless support for MongoDB and DocDB as a source

[AWS Database Migration Service Serverless](https://aws.amazon.com/dms/) (AWS DMSS) now supports MongoDB and Amazon DocDB as data sources. Using AWS DMSS, you can now migrate data from MongoDB and Amazon DocDB to a variety of data targets. AWS DMSS now shows MongoDB and Amazon DocDB as options when defining endpoints which can then be used as sources for data migrations. Additional information about AWS DMSS [sources can be found in our documentation](https://docs.aws.amazon.com/dms/latest/userguide/CHAP%5FSource.html).
