This pull request introduces significant improvements to the SKALE and Fair node provisioning system, focusing on expanding support for Fair nodes, enhancing Ansible playbooks for better modularity and clarity, and improving configuration and code quality. The updates make it easier to provision, manage, and clean up both SKALE and Fair nodes, and provide more comprehensive documentation and configuration options.

Documentation and Workflow Enhancements:

• Expanded the README.md with detailed instructions for Fair node provisioning, including step-by-step guides for setting up, migrating, and managing Fair nodes and their contracts. [1] [2] [3]
• Updated the bare-metal/README.md to clarify the default block device variable for VirtualBox VMs.

Ansible Playbook Improvements:

• Added new playbooks for Fair node workflows, including deploy_fair_manager.yaml, fair_migrate.yaml, create_chain.yaml, delete_chain.yaml, and others to support Fair-specific operations and modularize the provisioning process. [1] [2] [3] [4] [5] [6] [7]
• Improved backup and cleanup playbooks:
  • Enhanced backup_nodes.yaml and backup_schains.yaml to support both SKALE and Fair nodes, added validation, and improved task inclusion. [1] [2] [3]
  • Added cleanup_contracts.yaml and improved cleanup_sgx.yaml to support both node types and ensure proper cleanup. [1] [2]
• Updated archive.yaml to use build_type for conditional role execution, improving flexibility for source vs. image builds.

Configuration and Linting:

• Added .flake8, ruff.toml, and improved ansible.cfg for consistent code formatting, linting, and Ansible behavior. [1] [2] [3]

Python Script Refactoring:

• Refactored files/cleanup_contracts.py to:
  • Use the new SkaleManager and improved contract cleanup logic.
  • Add command-line arguments for selective cleanup (chains or nodes).
  • Improve logging, error handling, and environment variable usage.

Submodule Updates:

• Updated the helper-scripts submodule to the latest commit.
