IMPALA-11540: Add logs for ALTER_TABLE events that trigger slow metadata reload
ALTER_TABLE event could trigger full refresh on the table, which is
time consuming and can lead to event-processor lagging behind. We need
logs to show the difference between the before and after hmsTables so we
can further distinguish the cases that actully don't need a full table
refresh, e.g. changing the owner, changing tblproperties, etc.
Tests:
- Attach the process using IntelliJ to pause the metadata loading for a
while. So the metadata reloading of ALTER_TABLE event can exceed the
threshold. Manually verified the logs.
