[AutoTuner] add Dockerfile

[luarss]

This pull request introduces several updates to improve the Docker-based workflow and environment setup for the AutoTuner tool. Key changes include adding a Dockerfile for building a containerized environment, updating .dockerignore and .gitignore for better file management, and creating a Makefile to streamline Docker image building and uploading.

Docker Environment Setup:

• Added a new Dockerfile to define the containerized environment for AutoTuner, including steps to set up a Python virtual environment, install dependencies, and copy the source code.

File Management:

• Updated .dockerignore to exclude unnecessary files and directories such as .venv, __pycache__, *.log, and test files from the Docker build context.
• Updated .gitignore to include log files such as docker-build.log.

Build Automation:

• Added a Makefile to automate Docker image building, cleaning, and uploading, including support for tagging images and pushing them to Docker Hub.
