AWS DynamoDB + Baserow Integration

Keep AWS DynamoDB and Baserow aligned: use one app's database actions to perform the other's.

Example: use AWS DynamoDB's "Batch Get Items" action to perform Baserow's "Batch Create Database Table Rows" action. AWS DynamoDB has 21 actions (including Batch Get Items, Batch Write Items, and Create Backup); Baserow has 150 actions (including Batch Create Database Table Rows, Batch Delete Database Table Rows, and Batch Update Database Table Rows).
