[CI] Reduce runtime container image size

[Jeffwan]

Consolidate python images into one

Pull Request Description

1. Image size reduced by from 900MiB → 300MB. Separated profiling dependencies into optional group in
   python/aibrix/pyproject.toml
2. Unified Docker image from Dockerfile.python to consolidate all python images like runtime and metadata
3. Makefile and CI files updated to use the latest Dockerfile

just notice we remove the entrypoint in the dockerfile for share purpose. Instead, we need to have command in all kubernetes manifests in future.

  # Runtime
  docker run aibrix/runtime:latest

  # Metadata
  docker run aibrix/runtime:latest aibrix_metadata --host 0.0.0.0

  # Batch Worker
  docker run aibrix/runtime:latest aibrix_batch_worker --load-job-from-api

  # Downloader
  docker run aibrix/runtime:latest aibrix_download --model llama-3-8b

Summary of Changes

Hello @Jeffwan, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly optimizes the CI/CD process by reducing the footprint of Python runtime container images. It achieves this by consolidating multiple Python Dockerfiles into a single, efficient Dockerfile.python and by segregating large profiling-related dependencies into an optional group. This change not only slashes image sizes by two-thirds but also streamlines the build process and improves deployment efficiency for core services.

Highlights

• Reduced Container Image Size: The runtime container image size has been drastically cut from 900MiB to 300MB, a two-thirds reduction.
• Consolidated Python Images: All Python-based services (runtime, metadata, etc.) are now built from a single, unified Dockerfile.python, streamlining the build process.
• Optional Profiling Dependencies: Profiling and benchmarking tools' dependencies have been moved to an optional group in pyproject.toml, preventing their inclusion in standard runtime images and contributing to size reduction.

Code Review

This pull request effectively reduces the runtime container image size by consolidating multiple Python Dockerfiles into a single one and separating profiling dependencies into an optional group. The changes are well-executed and significantly improve image size and maintainability. I have one minor suggestion to improve a comment's clarity in pyproject.toml.
