fix(azure): catch import error as reportable

Adds the ReportableErrorImportError class to catch
a known issue with unhandled exceptions when importing 
crypt and passlib, but both are missing.

Fixes GH-#6770

Test Steps

• Create an Ubuntu 26.04 image with python3-passlib uninstalled
• Deploy this image to Azure
• Create a VM from the image, specifying an admin password
• View error:

OS Provisioning failed for VM {VM_NAME} due to an internal error: result=error|reason=error importing passlib library|agent=Cloud-Init/99.0.0-1~bddeb|\'error=ModuleNotFoundError("No module named \'\'passlib\'\'")\'

It would be great to capture the cloud-init log for the failure in your message to demonstrate the testing was done successfully.

Can you add a test case in:

• test_errors.py for this new class
• test_azure.py to demonstrate this. maybe look to test_query_vm_id_system_uuid_failure for inspiration

Thanks Cade!!

Thanks for the review @cjp256!

Added in tests in those two files respectively. Also, I added the output message from the VM to the commit message above. I'd be happy to make any additional changes as needed.

This should be ready for review; the SSH key error that is failing the pipeline seems to be occurring in Main as well. It should not be a result of this change.

@cadejacobson This doesn't merge cleanly. Please rebase on main branch.

[cadejacobson]

@holmanb I have merged in the most recent main and re-pushed. If it specifically requires a rebase, I would be happy to do that as well.

[holmanb]

That should suffice, thanks!

[holmanb]

This looks good to me. Thanks!
