Creating a DynamoDB Table

In this hands-on lab, we will create a DynamoDB table to store pet inventory data. In the scenario, the data architect on the team has requested a table definition with a partition key of `pet_species` with the data type `String`, a sort key of `pet_id` with the data type `Number`, and that the table be named `PetInventory`. Because the workload in development is not known, `On-Demand` provisioning should be utilized. We're free to create the table with any method we choose (web console, CLI/SDK, CloudFormation).
