Azure SGX2 support in public preview

[sanvol]

Hi,
Recently found out that Azure has had the public preview open for SGX2 capable VMs from November 2021. Everything seems to run out of the box. The earlier DCsv2 and DCdsv2-series run SGX1 and the new DCsv3 and DCdsv3-series runs SGX2.
https://docs.microsoft.com/en-us/azure/virtual-machines/dcv3-series
CPU: 3rd Generation Intel® Xeon Scalable Processor 8370C

To use the DCsv3 and DCdsv3-series instances with normal Microsoft account you need to request an increase of your quota of the instance type but at least for me the confirmation of completion came back the same day.

The following was run on a Standard_DC2ds_v3 instance.
