[Feature request] Adding README.md for all connectors like Grafana-connector

既存の grafana-connector の README.md から始め、iotdb-extras リポジトリ内の他の connector モジュールを調査します。既存の README をドキュメント構成として使用し、各モジュールについて概要、前提条件、ビルドとインストールの手順、使用例、設定パラメーターを取り上げます。すべての connector モジュールに同等のモジュールレベルのドキュメントが用意されれば完了です。

Motivation

While exploring the iotdb-extras repository, I noticed that the grafana-connector module has a README.md providing clear documentation on installation, usage, and configuration. However the other connector modules do not have equivalent module-level documentation. Developers and contributors landing on these modules have no quick reference for understanding their purpose, architecture, configuration, or usage without diving directly into the source code. Standardizing README documentation across all connector modules would improve contributor onboarding, reduce friction for new users, and bring consistency to the repository.

Solution

Add a README.md to each of the connector modules, following the same structure and style as the existing grafana-connector README:
Each README will cover module overview, prerequisites, build and installation instructions, basic usage examples, and configuration parameters — consistent with the existing grafana-connector documentation style.
