b41421cb1c [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.

d04cda0367 Fix QueryPlan lifetime (for EXPLAIN PIPELINE graph=1) for queries with nested interpreter
Example of such queries are distributed queries, which creates local
InterpreterSelectQuery, which will have it's own QueryPlan but returns
Pipes that has that IQueryPlanStep attached.

After EXPLAIN PIPELINE graph=1 tries to use them, and will get SIGSEGV.
