Consolidate multiple HW event messages affecting the same session in short time frame

While running a secondary migration of GDPS managed GM or MM pairs, there is the step after running the Prepare for Secondary Migration was processed.

This is where the external DR/CG solution should suspend the pairs before executing the Perform Secondary migration step. The old pairs are managed under the active CSM migrate_from_ session, which is automatically created during the Preparation command.

CSM logs an error event IWNR2055E for each individual pair that was suspended by external automation, therefore flooding the CSM console log with 1000's of messages for large migration sessions.

CSM should consolidate HW event messages per session when they occur in a short time frame (e.g. 10 seconds). This would reduce the console log to a single parent message, which can consolidate all current event messages as children message.

    This problem does not only affect the suspend message, but the other normal messages like IWNR2011I for the pair being started in the migrate_from session, that is being done in the Prepare for secondary migration step. Screenshot is showing those messages. Since that are pair messages CSM should be aware of when creating the migrate_from session, it is surprising why they are logged as individual message instead under a parent message for the migrate_from session.
