/**
* Handles the streaming a one or more section of one of more sstables to and from a specific
* remote node.
*
* Both this node and the remote one will create a similar symmetrical StreamSession. A streaming
* session has the following life-cycle:
*
* 1. Connections Initialization
*
* (a) A node (the initiator in the following) create a new StreamSession, initialize it (init())
* and then start it (start()). Start will create a {@link ConnectionHandler} that will create
* two connections to the remote node (the follower in the following) with whom to stream and send
* a StreamInit message. The first connection will be the incoming connection for the
* initiator, and the second connection will be the outgoing.
* (b) Upon reception of that StreamInit message, the follower creates its own StreamSession,
* initialize it if it still does not exist, and attach connecting socket to its ConnectionHandler
* according to StreamInit message's isForOutgoing flag.
* (d) When the both incoming and outgoing connections are established, StreamSession calls
* StreamSession#onInitializationComplete method to start the streaming prepare phase
* (StreamResultFuture.startStreaming()).
*
* 2. Streaming preparation phase
*
* (a) This phase is started when the initiator onInitializationComplete() method is called. This method sends a
* PrepareMessage that includes what files/sections this node will stream to the follower
* (stored in a StreamTransferTask, each column family has it's own transfer task) and what
* the follower needs to stream back (StreamReceiveTask, same as above). If the initiator has
* nothing to receive from the follower, it goes directly to its Streaming phase. Otherwise,
* it waits for the follower PrepareMessage.
* (b) Upon reception of the PrepareMessage, the follower records which files/sections it will receive
* and send back its own PrepareMessage with a summary of the files/sections that will be sent to
* the initiator (prepare()). After having sent that message, the follower goes to its Streamning
* phase.
* (c) When the initiator receives the follower PrepareMessage, it records which files/sections it will
* receive and then goes to his own Streaming phase.
*
* 3. Streaming phase
*
* (a) The streaming phase is started by each node (the sender in the follower, but note that each side
* of the StreamSession may be sender for some of the files) involved by calling startStreamingFiles().
* This will sequentially send a FileMessage for each file of each SteamTransferTask. Each FileMessage
* consists of a FileMessageHeader that indicates which file is coming and then start streaming the
* content for that file (StreamWriter in FileMessage.serialize()). When a file is fully sent, the
* fileSent() method is called for that file. If all the files for a StreamTransferTask are sent
* (StreamTransferTask.complete()), the task is marked complete (taskCompleted()).
* (b) On the receiving side, a SSTable will be written for the incoming file (StreamReader in
* FileMessage.deserialize()) and once the FileMessage is fully received, the file will be marked as
* complete (received()). When all files for the StreamReceiveTask have been received, the sstables
* are added to the CFS (and 2ndary index are built, StreamReceiveTask.complete()) and the task
* is marked complete (taskCompleted())
* (b) If during the streaming of a particular file an I/O error occurs on the receiving end of a stream
* (FileMessage.deserialize), the node will retry the file (up to DatabaseDescriptor.getMaxStreamingRetries())
* by sending a RetryMessage to the sender. On receiving a RetryMessage, the sender simply issue a new
* FileMessage for that file.
* (c) When all transfer and receive tasks for a session are complete, the move to the Completion phase
* (maybeCompleted()).
*
* 4. Completion phase
*
* (a) When a node has finished all transfer and receive task, it enter the completion phase (maybeCompleted()).
* If it had already received a CompleteMessage from the other side (it is in the WAIT_COMPLETE state), that
* session is done is is closed (closeSession()). Otherwise, the node switch to the WAIT_COMPLETE state and
* send a CompleteMessage to the other side.
