Describe the bug

When running this extension on a Mac using Apple Silicon, an error is thrown by UAMQP that the hardware is not supported.

To Reproduce

Use an Apple Silicon based Mac.
Install the az cli and the IoT extension
Try to use the extension, for example to monitor a hub

Expected behavior

It should work

Environment (please complete the following information):

This also appears to be a new issue - this was used earlier this year with no problems (before July 2021).

Update on working before - I wonder if the Azure CLI was running under Rosetta 2 before, so was ok with the x86_64 builds.

Issue raised for UAMQP for lack of Apple Silicon support: Azure/azure-uamqp-python#284

[jimbobbennett]

Update - I can make this work by:

• Creating a new virtual environment
• Installing uamqp in the virtual environment without using binaries, so it is rebuilt for arm64: pip install uamqp --no-binary uamqp --no-cache-dir
• Copying the uamqp folder from my virtual environment into the extension at `~/.azure/cliextensions/azure-iot'

So as a fix - can the setup code for this extension be changed to install uamqp with the no-binary flag? Not sure how to do this in a setup.py.

For me, this was a better approach than having to copy-paste with #468 (comment).
