Added the .ruff_cache/ entry to the .gitignore file to prevent Ruff's cache files from being tracked by Git. This change keeps the repository clean from unnecessary file tracking, which is particularly helpful for Python projects using Ruff for linting.
Introduced command-line flags for improved configuration management, including the creation of a default config file, and specified listening address override capabilities. This update facilitates easier and more flexible setup and deployment processes for the PostgreSQL connection exporter. The `.gitignore` and documentation were updated to align with these changes, reflecting the new command-line options and the removal of the `config.dist.yaml` in favor of creating a default configuration through the tool itself.
- Command-line flags `--create-config`, `--config`, `--host`, and `--port` added to streamline customization.
- Configuration now supports naming database hosts for clearer metrics identification.
- Documentation revised to guide through the new configuration and setup process.
- Changelog introduced to track project evolution.
These enhancements aim to make the exporter more adaptable to various deployment environments and to simplify the initial setup for users.
