Version the Game Services Cmdlets. Added new Get-AzureGameServicesCmdletsInfo cmdlet to display any general info about the cmdlets (only version number for now). Also added version number to a header which is sent with each request so that we can monitor how many users are on each version of the cmdlets.
Removed dependency on old Azure StorageClient DLL which could cause runtime issues on some systems without the Azure .NET SDK installed. Also added contract change to return VM package name with deployment report.
