Add remerge_sort_lowered_memory_bytes_ratio setting
...
Sometimes default ratio is not good enough (2), since it depends on lots
of factors:
- size of LIMIT
- max_memory_usage
- ...
So add a separate setting for it.
But note that it make sense to set
remerge_sort_lowered_memory_bytes_ratio only in range (1, 2]
Since <= 1 will just use more CPU, and > 2 will use more RAM and will
unlikely be faster.

[settings]: introduce new query complexity settings for leaf-nodes
...
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.

Optimize queries with LIMIT/LIMIT BY/ORDER BY for distributed with GROUP BY sharding_key
...
Previous set of QueryProcessingStage does not allow to do this.
But after WithMergeableStateAfterAggregation had been introduced the
following queries can be optimized too under
optimize_distributed_group_by_sharding_key:
- GROUP BY sharding_key LIMIT
- GROUP BY sharding_key LIMIT BY
- GROUP BY sharding_key ORDER BY
And right now it is still not supports:
- WITH TOTALS (looks like it can be supported)
- WITH ROLLUP (looks like it can be supported)
- WITH CUBE
- SETTINGS extremes=1 (looks like it can be supported)
But will be implemented separatelly.
vX: fixes

v3: fix extremes
v4: fix LIMIT OFFSET (and make a little bit cleaner)

Do not reserve extra threads after max threads optimization for simple queries
...
Before this patch pipeline.setMaxThreads() was called with 0 (since
streams.size() == 0, while pipes.size() == 1), which leads that
pipeline.getMaxThreads() returns max_streams.
While this threads were not used, they were reserved, which should not
happens either.
