1st Cleanup Week: Service Readme

[Xuanwo]

Most of our services README is out of maintaining.

We need to add the following parts about it:

• Useful badge, like what does in go-service-s3:

[![Build Status](https://github.com/beyondstorage/go-service-s3/workflows/Unit%20Test/badge.svg?branch=master)](https://github.com/beyondstorage/go-service-s3/actions?query=workflow%3A%22Unit+Test%22)
[![Integration Tests](https://teamcity.beyondstorage.io/app/rest/builds/buildType:(id:GoServiceS3_IntegrationTests)/statusIcon)](https://teamcity.beyondstorage.io/buildConfiguration/GoServiceS3_IntegrationTests)
[![License](https://img.shields.io/badge/license-apache%20v2-blue.svg)](https://github.com/Xuanwo/storage/blob/master/LICENSE)
[![](https://img.shields.io/matrix/beyondstorage@go-service-s3:matrix.org.svg?logo=matrix)](https://matrix.to/#/#beyondstorage@go-service-s3:matrix.org)

• Quick Start: How to init service/storager (via connection string)
• Docs: The links to go-service-s3 docs page

Please leave a comment if you want to take a part!
