commit 1f8ba4948d70ea1364def8e2bf8fea101b6fb583

[Fix](multi-catalog) add handler for hms INSERT EVENT. (#17933)
When we use a hive client to submit a `INSERT INTO TBL SELECT * FROM ...`
or `INSERT INTO TBL VALUES ...`
sql and the table is non-partitioned table, the hms will generate an insert
event. The insert stmt may changed the
hdfs file distribution of this table, but currently we do not handle this,
so the file cache of this table may be inaccurate.
