feat: infrastructure provisioning for load test environments

[kristopherjturner]

Overview

Implement infrastructure provisioning automation for spinning up load test VMs, configuring storage volumes, and managing cluster resources required for benchmark runs.

Scope

• PowerShell / Bicep templates for test VM provisioning on Azure Local
• Storage volume configuration for FIO and VMFleet workloads (CSV, raw disk, NVMe)
• Network configuration for iPerf throughput tests (dedicated VLAN/NIC isolation)
• Teardown automation to clean up test resources after each run
• Integration with azurelocal-toolkit variable registry for cluster parameters

Acceptance Criteria

• Test VMs can be provisioned from a single config-driven command
• Storage volumes correctly configured per test profile requirements
• Network isolation option configurable via YAML
• Teardown completes cleanly with no orphaned resources
• All provisioning steps logged to session log

Dependencies

• Parent Epic: [Epic] Load Testing Toolkit Full Build-Out #8
• Config & schema: feat: config & schema expansion for all load test profiles #9
• Core framework: feat: core framework modules (session, collector, logger, reporter) #10
• Toolkit variable registry: Create master variables registry to standardize variables across all repos azurelocal-toolkit#4

Related to AzureLocal/azurelocal-toolkit#16 (TKT-6) — Research: Azure Deployment Stacks for ARM/Bicep Deployments. Implementation of this issue should account for deployment stack adoption across all repos.
