API: Transaction history -to event stream-

[spikeekips]

(almost same with #3)

This api can be used to check how the transmitted transaction(from client) is finished,

• tx gets consensus successfully?
• or tx is failed because of some reason

---

• If tx gets consensus successfully, the response will have BlockTransaction data.
• If failed, the response will have BlockTransactionHistory data.

If a client get BlockTransaction or BlockTransactionHistory, there is no more data to be sent to the client i think.
Then, the server should drop the connection right?

@kfangw : If a client get BlockTransaction or BlockTransactionHistory, there is no more data to be sent to the client i think. Then, the server should drop the connection right? @spikeekips

If not in 'event-stream', connection should be stopped by server-side, but in 'event-stream', the server and client should stay put in connection and wait for newly added transactions, is it make sense?
