Version 0.4.0

Changes:
- put ObservabilityMiddleware before ExceptionHandlerMiddleware to avoid repetative code
- add application startup and last metrics update metrics along with CPU usage metric and threads count
- move host and port to new uvicorn section at config along with new reload and forwarded_allow_ips
- add request_id and remove trace_id/span_id generation if tracing is disabled
- move logging logic from utils to observability
- pass trace_id/span_id in HEX form
