HIVE-20291: Allow HiveStreamingConnection to receive a WriteId
This PR does the following:
* Extract some classes from HiveStreamingConnection and put them in the transaction package (`TransactionBatch`, `TxnState`). This was done because I was planning to add `UnManagedSingleTransaction` and it was going to result in a too big class
* Create `UnManagedSingleTransaction`, and make it inherit from `AbstractStreamingTransaction`, make `TransactionBatch` inherit from it as well.
* Allow `AbstractRecordWriter` to receive a `StatementIdChooser`. The implementation of `StatementIdChooser` can be tricky because it needs to try to provide a unique statement id but it can retry if this id is not unique. This may happen in several nodes at the same time. At the moment a naive implementation has been done.
