The check for Alter_info::ALTER_ADMIN_PARTITION implements this logic:
do not collect EITS STATS for this syntax:
ALTER TABLE ... ANALYZE PARTITION p
EITS statistics is global (not per-partition). Collecting global stats
is much more expensive processing just one partition, so the most
appropriate action is to just not collect EITS stats for this command.
