opentofu/terraform resources for secure bootable images on Azure

[yeoldegrove]

What would you like to be added:

We need changes to the upstream terraform provider for Azure to enable secure bootable images that let us bring our own secure boot config and keys.

Why is this needed:

I identified potential blockers to go forward with the openTofu implementation of our secure boot use cases.

• security_profile.uefi_settings needs to be passed to the shared image version
• https://learn.microsoft.com/en-us/python/api/azure-mgmt-compute/azure.mgmt.compute.v2023_07_03.models.galleryimageversionuefisettings?view=azure-python
• https://learn.microsoft.com/en-us/azure/virtual-machines/trusted-launch-secure-boot-custom-uefi
• Terraform azure shared_image_version resource

The terrafom shared_image_version resource cannot define uefi_settings at the moment.

• This can be implemented upstream.
