Support for SAS token based Authentication for Azure Blob Storage

Hi,

We have one use case where we want to provide limited access to objects in our storage accounts. We figured that the best way to do  this is by using SAS token based authentication mechanism to upload/download objects to Azure Blob Storage - SAS based Authentication

We found that JClouds client library provides support for Azure Blob Storage using account keys which might not fit our use case because of security reasons.
