Add pre-requisite checks for the CLI tool

[adnanhashmi09]

Description:

Before running the docker-compose watch command to set up the development environment, we should add some pre-requisite checks to ensure that the necessary components are available and the required files exist. This will help catch potential issues early and provide a better user experience.

Pre-requisite Checks:

• Check if the required ports are available (list the specific ports needed)
• Check if the Docker daemon is running
• Check if the docker-compose.yml file exists in the project directory
• Check if the Dockerfile.dev exists in the project directory

Implementation Steps:

1. Identify the required ports for the development environment and add a check to ensure they are not already in use.
2. Add a check to verify if the Docker daemon is running on the system.
3. Add a check to ensure that the docker-compose.yml file exists in the project directory.
4. Add a check to ensure that the Dockerfile.dev exists in the project directory.
5. Display appropriate error messages or prompts if any of the pre-requisite checks fail.
6. Proceed with the docker-compose watch command only if all pre-requisite checks pass.

Additional Considerations:

• Handle different operating systems (e.g., Linux, macOS, Windows) for checking the Docker daemon status.
• Provide clear instructions or guidance if any of the pre-requisite checks fail, such as suggesting solutions or troubleshooting steps.
• Consider adding unit tests for the pre-requisite check functions.
