Description

Summarize the changes made in this PR clearly and concisely.

Changes

1. Multi-Pipeline Support

• Before: 1:1 mapping - one pipeline per task in canary test
• After: 1:many mapping - automatically discovers and runs all pipelines whose names start with the task name

2. Performance Optimization

• Before: Multiple fetchPipelines() calls per task
• After: Single fetchPipelines() call at startup for efficiency

Example
For task WindowsMachineFileCopyV1, the system now automatically runs:

• WindowsMachineFileCopyV1 (default)
• WindowsMachineFileCopyV1_LegacyHost (legacy PowerShell)
• WindowsMachineFileCopyV1_NewFeature (feature testing)

Pull Request Overview

This PR refactors the task testing system to support multiple pipelines per task using name-based discovery and optimizes performance by reducing redundant pipeline fetches.

• Introduces automatic discovery of pipelines that share the task name.
• Reduces multiple fetch calls to a single pipeline-fetch at startup.

• [nitpick] The variable name 'allowParrallelRun' appears to have a typo; consider renaming it to 'allowParallelRun' for clarity.

  let allowParrallelRun = true;

change this to warning and use the original mesage from below - console.log(Cannot build and run tests for task ${taskName} - corresponding test pipeline was not found);
