implementation of itk service for setting up the tests within particular SDKs

[kdziedzic70]

Description

PR contains implementation of dockerized itk service that will be helpful in running itk tests across different SDKs: it enables user to mount the "current" branch to container. Assuming that implementation of itk-tailored testing agent is rooted in the repository - user than may execute the tests of "current" version - against the "stable" sdks that are included in the docker.

Summary of Changes

Hello, 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 introduces a foundational ITK test orchestration service designed to streamline the execution of integration tests across multiple SDKs. It provides a robust, containerized environment for running concurrent test scenarios, enhancing the efficiency and reliability of cross-SDK compatibility testing. The service leverages FastAPI for its API and integrates with existing test utilities to manage agent clusters and report test outcomes.

Highlights

• New ITK Test Orchestration Service: A new FastAPI service (itk_service.py) has been introduced to orchestrate and execute ITK test scenarios concurrently across various SDKs. This service manages the lifecycle of test clusters and reports results.
• Dockerization of the Service: A Dockerfile and .dockerignore have been added to containerize the ITK test orchestration service, simplifying its deployment and ensuring a consistent testing environment with pre-installed dependencies like Go and Node.js.
• Support for 'Current' Agent: The test suite now includes support for a 'current' agent, allowing the service to dynamically detect and spawn either Go or Python agents based on the presence of main.go or main.py in a dedicated 'current' agent directory.
• Dependency Updates: The uv.lock file for the Python v10 agent has been updated, specifically bumping the a2a-sdk and sse-starlette package versions.

Code Review

This pull request introduces a new FastAPI service (itk_service.py) designed to orchestrate and concurrently execute ITK test scenarios against a shared cluster, complete with API models for test cases and results. A new Dockerfile is added to build the service's Docker image, which includes installations for Go, Node.js, and Python dependencies managed by uv. Supporting files like .dockerignore, test_service.py, and test_service.sh are also added for environment setup and service testing. Additionally, the itk/test_suite is extended to support a 'current' agent type, with test_suite/current.py dynamically spawning either a Go or Python agent. A review comment suggests improving the RuntimeError message in test_suite/current.py to be more informative or to add a check for Docker environment usage.

[gemini-code-assist]

The RuntimeError message suggests this code is specifically for a Docker environment. Consider adding a check to ensure this module isn't accidentally used outside of Docker, or provide a more informative error message that guides users on how to set up the correct environment.
