Improved DynamoDB Initialization Patterns

[ashovlin]

We've released new ways to initialize the high-level DynamoDB clients in AWSSDK.DynamoDBv2 3.7.203. You can now provide the table's key and index structure in code, which allows the SDK to skip the implicit DescribeTable call that can lead to issues with cold-start latency, throttling, and thread-pool exhaustion.

This offers a workaround for #1476 and has been discussed there, but pinning an announcement here as well to help spread the word.

We encourage you to try the new TableBuilder for the document model and DisableFetchingTableMetadata for the object persistence model.
