Momento DynamoDB Interceptor

This crate offers an extension for the AWS SDK for DynamoDB that proxies requests through Momento.

You create a cache, then configure this interceptor, and your existing code that talks to DynamoDB through the AWS SDK continues to work as before. It's just hopefully a little quicker, cheaper, and without hot key troubles.

All reads serviced from this interceptor are potentially as stale as the TTL you configure. So if you set a ttl of 60 seconds, you might get 60 second stale responses from DynamoDB for a GetItem.
