[cookbook] [deployment] added cookbook showing how to deploy to the Microsoft Azure Website Cloud

The SensioLabs & Microsoft Azure staff recently collaborated to write this tutorial together to promote the Azure Website cloud platform. This tutorial is a step by step guide describing how to deploy a Symfony Standard Edition to Azure.

This tutorial has been written by the following team:

Hugo Hamon – Head of training – SensioLabs
Thomas Conté – Technical Evangelist – Microsoft
Benjamin Moulès – Technical Evangelist - Microsoft

In the near future, the goal is also to expand the Deployment section of the Cookbooks to other famous hosting providers.
