063f9cffab Allow memory profiler under sanitizers 
Only query profiler cannot work reliably with sanitizers (due to
unwinding from signal handler), but memory profiler should be fine.

Plus sometimes the problem appears only on build with sanitizers, so it
will be useful to have memory related profiling in trace_log.

Also there is a flaky check for stateless tests, that uses build with
ASan, and now trace_log there is empty, which sometimes does not allow
to debug further.

a218c3a28c Enable per-query memory profiler (set to memory_profiler_step=4MiB) globally 
Let's see at performance tests. And yes, they should show the
difference, if any, since they uses clickhouse python driver, which does
not knows about default settings, so new server will have this setting
set, while old server - upstream/master, will not.

9c20519f33 Add ability to disable converting expressions to local filter for external queries 
Sometimes it is undesirable to remove any expressions from WHERE, since
this may lead to reading the whole table, and this is pretty heavy job
for MySQL and PostgreSQL (even if you read only one column).

So external_table_strict_query had been introduced to prohibit this and
fail the query instead.

Azat Khuzhin
d610974c4c Set tcp_keep_alive_timeout to 300 by default 
This may fix possible issues with remote queries, when remote server
abnormaly terminates and the initiator does not have proper timeout.

This should not harm anything, since the timeout is pretty huge (300
seconds).

18e8f0eb5e Add ability to push down LIMIT for distributed queries 
This way the remote nodes will not need to send all the rows, so this
will decrease network io and also this will make queries w/
optimize_aggregation_in_order=1/LIMIT X and w/o ORDER BY faster since it
initiator will not need to read all the rows, only first X (but note
that for this you need to your data to be sharded correctly or you may
get inaccurate results).

Note, that having lots of processing stages will increase the complexity
of interpreter (it is already not that clean and simple right now).

Although using separate QueryProcessingStage looks pretty natural.

Another option is to make WithMergeableStateAfterAggregation always, but
in this case you will not be able to disable only this optimization,
i.e. if there will be some issue with it.

v2: fix OFFSET
v3: convert 01814_distributed_push_down_limit test to .sh and add retries
v4: add test with OFFSET
v5: add new query stage into the bash completion
v6/tests: use LIMIT O,L syntax over LIMIT L OFFSET O since it is broken in ANTLR parser
