* There are instances where share group delete calls in group coordinator (`onPartitionsDelete`, `deleteShareGroups`) where we lookup the metadata image to fetch the topic id/partitions/topic name for a topic name/id from the metadata image. However, there have been instances where the looked up info was not found due to cluster being under load or the underlying topic being deleted and information not propagated correctly. * To remedy the same, this PR adds checks to determine that topic is indeed present in the image before the lookups thus preventing NPEs. The problematic situations as logged * New tests have been added for `GroupMetadataManger` and `GroupCoordinatorService`. -- This is an automated message from the Apache Git Service.
