-------------------------------------------------------
Commit fa21bf61821199aedb4fbcdc1b09d0cf3ee56f51 in kudu's branch
refs/heads/master from Alexey Serbin

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.
