[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.
I think docs should always write things "Simply put". I think removing the first paragraph and using this paragraph as an intro is better. Or, change the order of these 2 paragraph so you have Simple > Advanced.
