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.
