Non trivial app code for test suites.

[jblevins1991]

Hello, I was looking at the code that was being executed after reading in the express.js benchmark page that the app did not scale well with additional cores. I don't think cores is always relevant to every single app out there. Node.js actually has a feature that allows you to cluster additional instances of a service together. But these are child processes. So cores doesn't matter when we are talking about a process. They don't translate to convey something meaningful.

The code for this app could also mimic the best case happy path that a company could hope to achieve. For example, we could use a setTimeout for 100ms to replicate going to a database and retrieving something and then return a json object. I would be happy to contribute this work as well!
