Create auto config file

Creates an auto config (executable) file for getting all the possible configurations done. It must include:

- Creating gitignore global file
- Setting git configs

Start by inspecting the repository for existing executable scripts or configuration entry points; no specific file or test is named. Define the auto-configuration command around creating a global gitignore file and setting Git configuration, then verify both operations complete successfully in a safe test environment.
