[157] Refactor of build processes and dependency management using Poetry

What?

GitHub Workflows Adjusted:
- release-pypi-build-push-package.yml, release-pypi-build-push-test-package.yml, tests-integration.yaml, and tests-unit.yml updated to improve CI/CD pipelines using Poetry.
Dockerfile and Makefile:
- Changes in the Dockerfile and Makefile to optimize build processes and integrate with new CI/CD setup.
Configuration Files:
- pyproject.toml and poetry.lock updated to use Poetry for dependency management, reflecting new dependencies and configurations.
- Transitioned coverage settings from setup.cfg (now deleted) to .coveragerc.

Removed Pipfile and Pipfile.lock as part of the move to Poetry.
Deleted old dev-specific requirements file dev-requirements.txt.
Removed setup.cfg and minimized setup.py, streamlining project setup and reducing redundancy.

Enhanced Project Configuration and Simplification:
- Centralizing configuration settings like coverage under .coveragerc simplifies modifications and updates, enhancing maintainability.
- Removing redundant configuration files (Pipfile, Pipfile.lock, setup.cfg) reduces clutter and focuses on using Poetry, which supports contemporary Python project standards.
CI/CD Pipeline Improvements:
- Updated workflow files to integrate with Poetry, improving build and test pipeline reliability and performance.
- New entry script and adjustments in Dockerfile/Makefile prepare the project infrastructure for more robust and scalable deployments.
Adherence to Modern Best Practices:
- Transition to Poetry for dependency management aligns with the latest practices in Python software development, aimed at improving project setup, dependency resolution, and package management.
