Duong updated RATIS-2009:
-------------------------
    Description: 
Today, a log entry can be either StateMachineLogEntry, RaftConfiguration, or 
Metatadata.
{code:java}
message LogEntryProto {
  oneof LogEntryBody {
    StateMachineLogEntryProto stateMachineLogEntry = 3;
    RaftConfigurationProto configurationEntry = 4;
    MetadataProto metadataEntry = 5;
  }
} {code}
However, after enabling zero-copy in appendEntries, only StateMachineLog 
entries are kept with a proper reference count. This is because request 
references count relies on `TransactionContext` to delegate, and 

> ReferenceCount should work for all LogEntry types.
