[autorevert] Add workflow restarts

[izaitsevfb]

Summary

Adds workflow restart capability to the PyTorch auto-revert tool, enabling automatic re-running of workflows for commits that match autorevert patterns but haven't been reverted yet.

Changes

• Added restart methods to WorkflowRestartChecker:

  • restart_workflow(): Restarts a workflow for a specific commit with duplicate prevention
  • Checks ClickHouse for existing restarts before attempting

• Enhanced autorevert-checker command:

  • Added --do-restart flag to enable automatic workflow restarts
  • Added --dry-run flag to preview restart actions without execution
  • Restarts workflows only for non-reverted commits matching autorevert patterns

• Fixed workflow naming consistency:

  • Normalized workflow names by removing .yml extension for ClickHouse queries
  • Added .yml extension only for GitHub API calls

• Updated do-restart command:

  • Now requires commit SHA (removed unused restart_latest_workflow)
  • Leverages same restart logic with duplicate prevention

Usage

  # Check patterns and restart workflows
  python -m pytorch_auto_revert autorevert-checker pull trunk --do-restart

  # Dry run to preview restarts
  python -m pytorch_auto_revert autorevert-checker pull trunk --do-restart --dry-run

  # Manual restart
  python -m pytorch_auto_revert do-restart trunk abc123def

Testing

python -m pytorch_auto_revert autorevert-checker inductor --hours 12 --do-restart --dry-run

I assume this API is available in the github main sdk we're already importing for this.
