Goal: 

The Manila API service uses oslo.service.wsgi.Server, which internally relies on eventlet for:

• Concurrent request handling via green threads
• Non-blocking I/O operations
• Connection pooling, pool size management, including reset operations
• Request dispatching to worker processes
• Process launching via service.ProcessLauncher
• Service coordination between workers
• Graceful shutdown handling

This spike will explore alternatives such as gunicorn or uwsgi, deprecating the native wsgi server's usage.

Acceptance Criteria:

• Identify code changes that will be necessary
