b20407fab9 Fix NOEXCEPT_SCOPE (before it calls std::terminate and looses the exception)
Current implementation of NOEXCEPT_SCOPE will not work, you cannot
rethrow exception outside the catch block, this will simply terminate
(via std::terminate) the program.
In other words NOEXCEPT_SCOPE macro will simply call std::terminate on
exception and will lost original exception.

But if NOEXCEPT_SCOPE will accept the code that should be runned w/o
exceptions, then it can catch exception and log it, rewrite it in this
way.

78bd47d8df Fix excessive LIST requests to coordinator for transactions
In [1] there was only few transactions, but lots of List for /test/clickhouse/txn/log:
