Daniel Bengtsson 5de514f1f8 Add threading backend implementation using cotyledon and standard threads
Introduces a new threading backend for oslo.service that provides a
complete alternative to the eventlet-based backend.

This backend includes:
	• A ThreadGroup and Thread implementation using the Python
	  threading module.
	• A reimplementation of all looping call utilities (
	  FixedIntervalLoopingCall, DynamicLoopingCall, etc.) using
	  threading.Event and futurist.ThreadPoolExecutor.
	• A service management layer based on cotyledon, including
	  Service,ServiceWrapper, Launcher, and ProcessLauncher.
	• A new ThreadingBackend class that exposes all components
	  needed for integration into oslo.service.

This change provides a robust and eventlet-free alternative backend while maintaining API compatibility.
