KUDU-2612: fix txn keepalive failover in Java client
Prior to this patch, transaction keepalive heartbeater in Java client
wouldn't switch to a different TxnManager instance fast enough when
current TxnManager is no longer available (e.g., corresponding Kudu
master stopped or shutdown). That might lead to unintended termination
of a multi-row transaction if a leader master was shutdown while the
transaction was in progress. The issue was due to:
* using long timeout (i.e. the default one) for issuing
KeepTransactionAlive RPCs
* sending KeepTransactionAlive RPCs synchronously on the client's
HashedWheelTimer timer which was supposed to run only short tasks
This patch fixes the issue mentioned above and adds a new test scenario
which verifies that Kudu Java client switches to a different TxnManager
instance when the previously used one is no longer available.
