Move integration tests into their own project. This makes it easier to run unit tests if you don't want to (or don't have) `azurite` running, since you can `dotnet test` just that directory.
Also add a check into the `AzuriteStorage` class that will abort the entire test run if `azurite` is not running, which is simpler than reading lots of socket exceptions.
