Pull request overview
Adds support for a new --processor-mode argument across az vm and az vmss command flows, enabling users to set the Compute RP hardwareProfile.processorMode property during create/update and validate it via show output.
Changes:
- Introduces
--processor-mode(Deterministic/Opportunistic) forvm create/updateandvmss create/update. - Wires the new argument into VM/VMSS request construction (ARM template builder + update payload shaping) and internal snake_case conversion helpers.
- Adds a live-only scenario test covering create/show/update for both VM and VMSS.
