Improve Celery config print on start-up
This fixes #54 (closed).
During testing of lifespan.py, the following import errors were encountered:
ewoksserver spitoni@linspitoni:~/ewoksserver/src$ python3 ewoksserver/app/lifespan.py Traceback (most recent call last): File "/home/spitoni/ewoksserver/src/ewoksserver/app/lifespan.py", line 13, in from .backends import json_backend ImportError: attempted relative import with no known parent package
These issues can be resolved by prefixing the imports on lines 13 to 17 with ewoksserver.app. This update ensures correct module resolution within the application structure.
