GEODE-10412: Clear expired tombstones during region destroy (#7838)
* GEODE-10412: Clear expired tombstones during region destroy
The issue:
During region destroy operation, the expired tombstones aren't cleared
when non-expired ones are available. Later, these expired
tombstones prevent all other regions' tombstones from being cleared
from memory, causing many issues (memory and disk exhaustion).
The solution:
When a region is destroyed, it must clear all the related expired and
non-expired tombstones from memory.
* Add distributed test that reproduce the issue
* Update after review
> Destroy region command doesn't clear the region related expired tombstones

> Tombstones in geode are kept on two maps: expiredTombstones and tombstones
> (non-expired ones). When a region is destroyed, it must clear all the related
> expired and non-expired tombstones from memory. Due to the below code bug,
> expired tombstones aren't cleared when non-expired tombstones are available
> during the region destruction:
> {code:java}
> private boolean removeIf(Predicate<Tombstone> predicate) {
> return removeUnexpiredIf(predicate) || removeExpiredIf(predicate);
> }
> {code}
> Because of the above, non-expired tombstones are never removed from memory,
> preventing other tombstones from being cleared. Since other tombstones never
> expire, the compaction is not done, and therefore the disk is filled, causing
> the issues.
