Aleksandr Chesnokov updated IGNITE-28712:
-----------------------------------------
Description: From docs for GridClusterStateProcessor#compatibilityMode:
"Compatibility mode flag. When node detects it runs in heterogeneous cluster
(nodes of different versions) it should skip baseline topology operations."
Looks like we chose another way for implementing Rolling upgrade (was: It
seems that {{StartRoutineDiscoveryMessage}} duplicates
{{StartRoutineDiscoveryMessageV2}} and should be removed if possible.
Currently, {{StartRoutineDiscoveryMessage}} is mutable, but V2 is not.)
