Proposal: Redis example

[salaboy]

Changes

• 🎁 After building like 5 functions using Redis as the data store, I think that there is a value in providing an example here to help users quickly bootstrap a project with all the dependencies. I've tried to maintain the "echo" idea.. for this case, getting the request body, writing it with an echo in a Redis Key, and then reading it and return it back to the response body.

The big problem that I am facing is that testing complicates the example code a lot. So I am open to suggestions on how to simplify that side of the example.
