IGNITE-7506 establishing of BaselineTopology in compatibilityMode when old nodes left the cluster

> Project: Ignite
> Issue Type: Bug
> Reporter: Sergey Chugunov
> Assignee: Sergey Chugunov
> Priority: Major
>
> When Ignite node of version 2.4+ joins cluster with older versions of Ignite running it sets *compatibilityMode* flag to handle **cluster state in a special way (excluding BaselineTopology from discovery exchange process and so on).
> But when all old nodes are turned off there is no way except full cluster restart to enable setting very first **BaselineTopology.
> This should be addressed and some way to exit compatibilityMode without full cluster restart should be provided.
