Implement Docker Compose Setup and Test Execution Script

[hackintoshrao]

This pull request introduces a comprehensive Docker Compose setup for our application and a corresponding shell script to manage the execution of tests.

The key changes include:

1. Creation of a docker-compose.yml file:

This file defines two services: qdrant and tests.
The qdrant service is configured to use the qdrant/qdrant image and exposes the necessary ports.
The tests service is configured to use the rust:1.55 image and runs the test command in the appropriate working directory. It also depends on the qdrant service being healthy before starting.

2. Creation of a shell script for test execution
   The script checks for the presence of Docker and Docker Compose.
   It navigates to the directory containing the docker-compose.yml file.
   It accepts an optional --build flag. If provided, the script rebuilds the Docker images before starting the services and running the tests.

It starts the Docker Compose services, runs the tests, and then tears down the services.
These changes allow for a streamlined and flexible testing process, making it easier to incorporate code changes and manage the lifecycle of the services involved in testing.

Please review these changes and provide any feedback.

This looks good overall, I've noted an organizational change to where the script is, if that change could be made, then this is ready.

This would be better located in /toolchain/scripts for consistency, and could be named run_qdrant_tests.sh. The other scripts there have a pattern for executing from the root of the repo as their cwd.
