Add Dockerfile and CI workflow for Docker build

[siddharth7113]

Pull Request:

This pull request addresses the implementation of a Dockerfile and a CI workflow to build and test the neso-solar-consumer application using Docker. The last command runs the neso_solar_consumer.app module, as requested.

Fixes: #13

Changes Made:

1. Added a Dockerfile to create a lightweight Docker image:
   • Base image: python:3.12-slim.
   • Dependencies are installed using pip with requirements.txt.
   • Entry point defined as neso_solar_consumer.app.
2. Created a CI workflow (docker-build.yml) in .github/workflows to:
   • Automatically build the Docker image on every push.
3. Incorporated requirements.in, requirements.txt, and dev-requirements files for dependency management.

Note: This branch includes changes from issue #6, which is pending merge. These changes are necessary for testing the Docker build and running the application. Once #6 is merged, these changes will align with the main branch.

---

Testing:

• Docker image successfully built locally using the command:

  docker build -t neso-solar-consumer .

• The application runs as expected in the container:

  docker run --rm neso-solar-consumer
