We can create a CreateStorageManagementChannel in the ServiceManagementHelper2, but we won't be able to use the same `new WebChannelFactory<T>` method as is used in the ServiceManagement and Sql Cmdlets currently, we'd have to return a class wrapping around BlobClient instead.
For the Storage Cmdlets we don't intent to call the various REST APIs directly, but instead use the functionality exposed by the BlobClient API as it offers a lot of added functionality that we'd otherwise have to roll by ourselves.
