Add response time to resposne

[tmaiaroto]

Perhaps add a response time to the responses? This may help a user decide when they need to scale their storage engine (DynamoDB read/write capacity units for example).

However, I'm not certain it's a huge concern here since AWS can (recently announced, https://aws.amazon.com/blogs/aws/new-cloudwatch-events-track-and-respond-to-changes-to-your-aws-resources/) trigger Lambdas based on various events to automatically scale. Up and down.

That's all set by the user outside of discfg and is not a discfg concern. Especially if using a different storage engine that does not have these kind of settings for scale (S3 for example).

Regardless, it's useful to know a response time. Whether it's for capacity planning (something we're trying alleviate with discfg by design) or just for the needs when designing an application. I do believe response time is going to be a tradeoff for other features with discfg.
