KUDU-2612: propagate commit timestamp (Java client)
With this patch, the commit timestamp for a non-empty multi-row
transaction is propagated to a Kudu Java client upon calling either
KuduTransaction.isCommitComplete() or KuduTransaction.commit(true).
The former propagates the timestamp for the case of committing a
transaction asynchronously, the latter works for the synchronous case.
Updating the last observed timestamp with the commit timestamp is
necessary to achieve consistency in the READ_YOUR_WRITES mode when
reading the data of a transaction which has just been committed. The
commit phase might take some time and may even be retried in some cases,
so even if the client observed timestamps for all the write operations
it sent in the context this transaction, the maximum timestamp collected
among the involved transaction participants might be far ahead of the
last timestamp observed by the client so far.
In addition, this patch addresses the most prominent cause of flakiness
in the recently introduced scenario
TestKuduTransaction.testTxnKeepaliveRollingSwitchToOtherTxnManager.
This patch is a follow-up to e495d6bb759fdae7cd001d86df3bae5c4f5f2b36.
