SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior
/home/jenkins-slave/workspace/kudu-master/1/src/kudu/util/monotime.cc:220:10 in
Previously, we converted an initial deadline to a timeout, potentially
rejiggering the value in case of the maximal timeout, and then
recomputed the deadline. This patch addresses the UB by addressing a
TODO to pass deadlines in the context of the TxnSystemClient instead of
timeouts.
