feat: Add a new database driver for Amazon DynamoDB

[passren]

SUMMARY

There is no database driver for Amazon DynamoDB so far. I developed a Python DB API 2.0 (PEP 249) client for Amazon DynamoDB and did some work to be compatible with Superset. My Project is here. The latest version is 0.4.2 which have already supported Superset connector.
