title: Proper CloudTableClient instance lifecycle?
body: <p>I'm using the new WindowsAzure.Storage 2.0 (might not be a revelant information), and I'm implementing data access using CloudTableClient. Most samples I've seen are instanciating a CloudTableClient in the ctor of an ASP MVC Controller (instanciated per web request).
  Is there any performance penalty doing so?
  Would it be wise to keep a long running instance in a singleton style?</p>
