Long running test pipeline for AKS swiftv2 clusters.

[sivakami-projects]

test:
This PR introduces a new Azure DevOps pipeline for running long-term tests on AKS Swift v2 clusters.
The pipeline automates the creation of AKS clusters and the necessary networking infrastructure.

1. Create 2 AKS clusters and attaches node pool with 2 nodes with 8 NICs on each node. All are AKS managed Linux nodes.
2. Creates 4 VNets and subnets.
3. Peers three of the four VNets.
4. Creates 2 storage accounts with private endpoints.
5. Adds NSG rules to prevent network connectivity between pods on two subnets in the same Vnet.

Initial PR - #4092

• Creates a parameterized pipeline template that orchestrates AKS cluster creation and networking setup
• Implements bash scripts to provision two AKS clusters, virtual networks, network peerings, storage accounts, and network security groups
• Configures parallel execution for AKS cluster creation to optimize deployment time

Pull Request Overview

This PR introduces automated infrastructure provisioning for long-running tests on AKS Swift v2 clusters. The implementation creates a complete testing environment including AKS clusters, virtual networks, storage accounts, and security controls through Azure DevOps pipelines.

Key Changes:

• Creates a parameterized Azure DevOps pipeline template that orchestrates infrastructure deployment across three jobs
• Implements bash scripts for provisioning Azure resources including AKS clusters, VNets, peerings, storage accounts, NSGs, and private endpoints
• Configures parallel AKS cluster creation to reduce deployment time

I think you'll want to change the branch this PR is on
Right now, it's on sivakami-project:long-running-pipeline-test-branch, which is a fork of this repo
I don't think the PR checks and all that let the users run pipeline tests from forks anymore, it has to be a branch from this repo itself

Kind of like you had in #4092, that branch was just long-running-pipeline in this repo
