Review request for Flume and Hari Shreedharan.
Changes
-------

hi Hari,
   Great thanks for your advice. I changed the code template and deleted additional blanks and whitespaces.
   ScribeSource is responsibility for existing Scribe, importantly, it can adopt the user interface with Scribe.
   User who wants to use ScribeScource may have the Scribe instance in there old ingest system.

   How can we test ScribeSource from Java code? Here is example:

   TSocket socket = new TSocket("Flume server address", 1499, 10000);
   socket.open();

   TTransport transport = new TFramedTransport(socket);
   TBinaryProtocol protocol = new TBinaryProtocol(transport, false, false);

   Client client = new Client(protocol);

   List<LogEntry> list = new ArrayList<LogEntry>(n);
   for (int j = 0; j < 100; j++) {
     list.add(new LogEntry("catogory", "message"));
   }

   client.Log(list);//Sending Scribe entry to Flume with Thrift

   transport.close();
Description
-------

There may someone like me that want to replace central Scribe with Flume to adopt existing ingest system, using smooth changes for application user.
Here is the ScribeSource put into legacy folder without deserializing.
This addresses bug https://issues.apache.org/jira/browse/FLUME-1382.

Testing
-------

I already used ScribeSource into local environment and tested in past week. It can use the existing local Scribe interface
Thanks,
