if the txn which access tables under mo_debug database starts just after tn upgrade, the context will be timeout when sending sub table request, because the timeout is 30s and tn upgrade lasts longer than that. so change it to 5m. Approved by: @zhangxu19830126, @sukki37
1.Refactor the remote execution function and add more logging for it. If the data-receiver prematurely terminates the query, it will always notify the sender to cease operations before closing the connection. 2.Remove numerous fields from the pipeline's Message. 3.Add comments to some obscure code sections.

1, leak原因： profile 和 日志的信息对不齐，现在具体什么原因不确定。 leak现状： 3996 是在v1.2.2-20240715 上出现的。在这个版本之后，已经做了leak方面的下述修改，已经合并在1.2-dev最新的代码中。 后台执行都换成autocommit = true。 后台执行结束清理资源时，会强制结束事务。 修改检查udf function的奇怪逻辑。 leak修改： footprints直接记录到txnoperator. 能实时记录事务走过那些函数。避免之前要复制的情况。 2, load data local问题原因： 一种可能原因，在计算引擎还未从pipereader读数据时， 就kill load data local. 然后计算引擎退出，未关闭pipereader. 之后pipewrite.Write阻塞，导致未从load data local退出。 修改： 在load local启动时，启动一个哨兵线程，接受ctx信号。如果ctx在kill时被cancel，立即关闭pipereader. 让pipewriter.write退出。 3, 将incrStatement和rollbackLastStatement的卡住单独列出来，而不含在`found leak txn`。 leak checker新增下述日志。 ``` found txn in incr statement found txn in rollback statement ``` 4, 将dropAccount中执行的sql落日志。 Approved by: @XuPeng-SH, @zhangxu19830126, @qingxinhome, @reusee, @sukki37, @triump2020, @aptend

…le (matrixorigin#18787) In the case of "load data local infile" statement, client sends the first packet, then server sends response, which is "0xFB + filename", after that, client sends content of filename and an empty packet, at last, server sends OK packet. The sequence ID of this OK packet is not 1, and will cause the session cannot be transferred after this stmt finished. So, the solution is: when server sends 0xFB and the sequence ID of next packet is 3 bigger than last one, the next packet MUST be an OK packet, and the transfer is allowed.
