azure-iot-hub vs azure-iot-sdk and identity.

Hi team,

First question, since we rely on IotHub for our daily ops and we are building services and processes around it, we would like to know if this library **azure-iot-hub** is the way to go or it has been deprecated, since it looks stale and we should favor **[azure-iot-sdk](https://github.com/Azure/azure-iot-sdk-python)**?

Second to that, we are trying to get rid of all connection string as much as possible. Our middleware, runs on Azure and the webapp has all the needed permissions to operate the IoTHub, create new devices, change device twin definition, check the state of devices and send direct methods. With that in mind, we haven't been able to integrate [azure-identity](https://pypi.org/project/azure-identity/). Does the library support Identity using something like `DefaultAzureCredential` from the **azure-identity** package? If identity is a possibility, do you mind sharing an example?

Kind regards,
Alejandro
