Distributed Data Platform on Azure Virtual Machines

.SYNOPSIS 
  Creates a Linux Virtual Machine for use with distributed data platform deployments on Azure virtual machines. 
.DESCRIPTION 
  Used to automate the creation of Windows Azure VMs to support the deploying distributed data platforms  
  on Windows Azure Virtual Machines.  This script will be run from master scripts.

  The virtual machines will be named based on a prefix.  The VMs are distributed evenly across the cloud services.
  Each VM will have attached data disks that are written to a storage account defined in the variable array. 
  All OS disks are written to the default storage account where the image is stored.
