> During the RU process, updated nodes operate in accordance with both the old
> logical version (prior to RU completion) and the new one (after RU
> completion). We need to store the features of the previous version under
> which this node operated.
> If a node joins the cluster after the Rolling Upgrade has been finalized,
> this value is inherited from the existing cluster nodes. After Rolling
> Upgrade finalization, all cluster nodes are guaranteed to hold it the same.
> This feature set is used to adjust the serialization process during a Rolling
> Upgrade and after it has been finalized.
