/**
* Marker interface for all operations used in Raft system.
* {@code RaftSystemOperation} extends a few interfaces to bring in some extra
* features:
*
* - {@code AllowedDuringPassiveState}: Raft operations are submitted while
* a node is shutting down to replace shutting down member with a new one.
*
* - {@code ReadonlyOperation}: Raft operations are executed on partition
* threads but not sent to partition owners. To avoid invocations fail with
* {@code PartitionMigratingException}, we mark them as read-only from
* Hazelcast partitioning system perspective.
