ShardingSphere-proxy ### Expected behavior first and second connection opened successfully ### Actual behavior When I User MySqlConnector(.net standart2.0) instead of Mysql.Data(From oracle) and try to conect to proxy at second time. It happened as below.(first try was success, close and open again will throw the error) I can only use MySqlConnector beacuse of Pomelo.Entityframework.Codeļ¼and it excute sql in real async mode(oracle's always in sync mode). I check the source code, and find the error stacktrace was in ServerSession.cs 507th line. ### Reason analyze (If you can) It work well when I use mysql 8.0.20 directly. I suppose that the proxy does not support this command. which use in MySqlConnector SDK to get better performance ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. VS2019 Create a Cosole project Install MySqlConnector Nuget package Create a Mysqlconnection. open once and close. then open again, you will get this error ### Example codes for reproduce this issue (such as a github link).  https://github.com/mysql-net/MySqlConnector ServerSession.cs 507 whent it try TryResetConnectionAsync   Please, .net also need your help -- This is an automated message from the Apache Git Service.
