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:

    $ clickhouse-local --format TSVWithNamesAndTypes --file zookeeper_log.tsv.gz -q "select * except('path|session_id|event_time|thread_id|event_date|xid') apply(x->groupUniqArray(x)), path, session_id, min(event_time), max(event_time), count() from table where has_watch and type = 'Request' group by path, session_id order by count() desc limit 1 format Vertical"
