Go Kit example

This repo exists just to play with go-kit, to get a better understanding of what it can offer.

• First commit contains the most basic example ever that you can build.

• Second commit have additional logging middlewares and corrects some errors from the previous example

• Third commit added instrumentation / metrics

A "review"

The whole idea is:

• stuff is modular and pluggable
• we wire things in the main of the application. This includes logging, instrumentation and definition of routes
• we create one handler per route. The handlers are initialized with the NewServer function
• All the logic is cleanly separated in service.go. This means it's easy to rewrite the rest.
• Being mostly interested in the HTTP part, having logic on error code in transport.go sounds a bit weird.
• The middleware are tied to the interface they are wrapping. This means that it is probably better to have only one interface for all the operations of our microservice.
