Bug#14111584 PB2: PERFSCHEMA.AGGREGATE FAILS ON PB2 SPORADICALLY

Permanently removed test case perfschema.aggregate.

The Performance Schema is generally lock-free, allowing for
race conditions that might arise from multi-threaded operation
which occasionally results in temporary and/or minor variances
when aggregating statistics. This test needs to be redesigned
to accommodate such variances.

-# - COUNT/SUM/MAX(events_waits_summary_global_by_event_name) >=

-# For example, a MyISAM table removed from the table cache
-# will cause a mysql_mutex_destroy on myisam/MYISAM_SHARE::intern_lock.
-# Another example, a thread terminating will cause a mysql_mutex_destroy
-# on sql/LOCK_delete
-# Both cause a row to be deleted from events_waits_summary_by_instance.

-# Likewise:
-# - COUNT/SUM/MAX(events_waits_summary_global_by_event_name) >=

-# - MIN(events_waits_summary_global_by_event_name) <=
-#   MIN(events_waits_summary_by_thread_by_event_name)
-# There will be equality only when no thread is removed,
-# that is if no thread disconnects, or no sub thread (for example insert
-# delayed) ever completes.
-# A thread completing will cause rows in
-# events_waits_summary_by_thread_by_event_name to be removed.
