Change subject: KUDU-2612 keep-alive tracking for transactions ...................................................................... KUDU-2612 keep-alive tracking for transactions This patch introduces the functionality of tracking the liveness of a distributed multi-row transaction into TxnStatusManager and provides corresponding proxy methods in TxnManager, so a Kudu client now can send keep-alive requests for a transaction (the implementation of the latter is planned in a follow-up patch). >From the TxnStatusManager, the newly introduced keep-alive RPC is represented as another type of CoordinateTransaction() request: CoordinatorOpPB::KEEP_TXN_ALIVE. New tests to cover the existing functionality are added as well. More end-to-end tests will be added by follow-up changelist once Kudu C++ client starts sending keepalive requests for started transactions. Also, all newly introduced tests in txn_status_manager-itest.cc are disabled because without [1] they are a bit flaky. I added TODO to re-enable those once [1] is committed.
