alpine镜像集成常用数据库客户端

业务需求，做一个包含各种命令的容器，所以基于alpine操作系统做了个镜像，包含：curl、openssl、openjdk17、postgresql16-client、mysql-client、mssql-tools

由于alpine官方镜像源里没有mssql-tools的包，参考了微软官方文档：https://learn.microsoft.com/zh-cn/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server?view=sql-server-ver16&tabs=alpine18-install%2Calpine17-install%2Cdebian8-install%2Credhat7-13-install%2Crhel7-offline，以及github上开源项目：https://github.com/croblesm/mssql-tools-alpine，自己做了一个mssql-tools18版本的镜像

话不多说
