Add ability to log when max_partitions_per_insert_block is reached (#50948)
* Add ability to log when max_partitions_per_insert_block is reached

There's plenty of reasons to drop max_partitions_per_insert_block
down from it's default of 100, with the main one being even touching
remotely close to this number of partitions will create a lot of
merge activity that can de-stabilise a cluster.

This commit adds the ability to log when the above limit is reached
rather than throw an exception, so that you can gauge the impact on
users when dropping this value down.

Update query-complexity.md
The docs say that max_memory_usage is set to 10GB in the default config, but max_memory_usage does not appear in the default config, so the default is unlimited.

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.
