Only queries slower then the value of this setting will go to system.query_log,
i.e. something like slow_query_log in mysql.
v2: log_queries_min_time renamed to log_queries_min_query_duration_ms
v3: add current_database into system.query_thread_log
v4: rewrite test using current_database
v5: fix query_duration_ms in system.query_thread_log
* for CSV and TSV input formats input_format_csv_enum_as_number,
input_format_tsv_enum_as_number settings should be enabled in order to
treat input value as enum id
The new setting should allow to control query complexity on leaf nodes
excluding the final merging stage on the root-node. For example, distributed
query that reads 1k rows from 5 shards will breach the `max_rows_to_read=5000`,
while effectively every shard reads only 1k rows. With setting `max_rows_to_read_leaf=1500`
this limit won't be reached and query will succeed since every shard reads
not more that ~1k rows.
Possible values:
- 1 - Do not merge aggregation states from different servers for distributed query processing - in case it is for certain that there are different keys on different shards.
- 2 - same as 1 but also apply ORDER BY and LIMIT stages

Before this patch there was:
- parallel_distributed_insert_select=1, that executes:
INSERT INTO dist_out SELECT ... FROM underlying_dist_in
After this patch there will be:
- parallel_distributed_insert_select=2, that executes:
INSERT INTO underlying_dist_out SELECT ... FROM underlying_dist_in
And cover the behaviour w/o integration test, by using the following
techincs:
- SYSTEM STOP DISTRIBUTED SENDS
- prefer_localhost_replica=0
