WIP KUDU-2612 tablet servers automatically register txn participants
With this patch, tablet servers automatically register tablets as
transaction participants upon receiving write operations targeting
tablet replicas they host.
This patch also contains several test scenarios to cover the newly
introduced functionality.
TxnOpDispatcher entry lifecycle:
* An entry is added upon receiving write request in the context
of a multi-row transaction.
* An entry is removed upon applying either ParticipantOpPB::ABORT_TXN
or ParticipantOpPB::FINALIZE_COMMIT operation.
* If a write request is received after transaction has been committed
or aborted, the entry is automatically removed once receiving
corresponding error response from any of the following components:
** from TxnStatusManager in at attempts to register a participant
in the context of committed/aborted transaction
** from the replica itself in an attempt to add
ParticipantOpPB::BEGIN_COMMIT operation
Those rules allows for automatic clean up of TxnOpDispatcher entries.
WIP:
* put more details into the commit description
* clean up the code: renaming, in-line docs, etc.
* more tests
