There was an issue with go-mysql-driver that a connection returns an error "invalid connection."
article: https://github.blog/2020-05-20-three-bugs-in-the-go-mysql-driver/
And the author of the article fixed it go-sql-driver/mysql#934.
If driver.SessionResetter is implemented, returns ErrBadConn instead of ErrInvalidConn, then it retries to establish a new connection again.
So I added ResetSession to tracedConn to avoid the error occurring.
