Description

KIP-915 introduced flexible versions to the records used for the group and transaction coordinators.
However, the KIP did not update the record version used.

For KIP-890 we intend to use flexible fields in the transaction state records. This requires a safe way to upgrade from non-flexible version records to flexible version records.

This change is implemented via MV or through a new feature type.
