shared class "CananonicalizedString" used in Authentication Utility is in StorageUtilities.cs

I was looking to use this for posting data to EventHub but getting a reference error for the shared Authentication utility for the CanonicalizedString class. It is contained in the StorageUtilities.cs script so there is a "shared script" with a dependency on StorageUtilities, I moved the class reference from StorageUtilities to Authentication Utility and it worked, all g just an FYI
