Add optimize_distributed_group_by_sharding_key and disable it by default
...
I know at least one way to fool that optimization, by using as sharding
key something like `if(col1>0, col1, col2)` (although this is not common
sharding key I would say, but can be useful if this will work
correctly), so let's disable it by default.

Use thread pool (background_distributed_schedule_pool_size) for distributed sends
...
After #8756 the problem with 1 thread for each (distributed table, disk)
for distributed sends became even worse (since there can be multiple
disks), so use predefined thread pool for this tasks, that can be
controlled with background_distributed_schedule_pool_size knob.
