Change subject: WIP KUDU-2612 keep-alive txn heartbeating for C++ client
......................................................................


Patch Set 2:

I think being able to serialize/deserialize transactions provide great 
flexibility. Will the Java Transaction object send heartbeat messages as well? 
If so, we could just keep it in a container until the end of the transactional 
session and commit at the end, similarly to how Impala heartbeats Hive ACID 
transactions.
Do we need to create transaction objects to write data or can we just use the 
txn token? Because if we need to create multiple transaction objects (e.g. in 
multiple Impala executors), we might need to tell them not to send heartbeats 
because we are already heartbeating from somewhere else.
