Clean up of the EventHubsCaptureEventGridDemo sample in the azure-event-hubs repo

[zedy-wj]

• The WindTurbineDataGenerator project does not use the old EH package anymore, but it does list it in the packages.config file and the csproj file
• The FunctionEGDWDumper project lists Azure.Storage.Blobs (the new Storage package) in the csproj file, but uses the older Microsoft.WindowsAzure.Storage package in the Function.1.cs file
• The DWDumper project lists the older Key Vault package in the csproj file, but does not use it anywhere in code
• The DWDumper project also uses the older Storage package. It should use Azure.Storage.Blobs instead

l have updated these file, and use new package Azure.Storage.Blobs in DWDumper project.
