This could resolve this restriction as well

@myc2h6o the limitation mentioned above ~> **NOTE:** An IoT Hub can only be updated to use the System-Assigned Managed Identity for file_upload since it is not possible to grant access to the endpoint until after creation. can be worked around within that resource by having the Create method call the Update method - so I'm not sure why we're pushing that limitation onto end-users?

Hi @tombuildsstuff thanks for reviewing! For the limitation, it involves two resources: both the azurerm_iothub and the azurerm_role_assignment thus not able to workaorunding it in the iothub resource itself. We need to create the iothub with SystemAssigned identity first, then create a role_assignment to assign the Storage related role to the identity, and only after that can we update the iothub to set the file_upload to use the SystemAssigned identity.
