10b4f3b41f 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
v2: fix WITH *
v3: fix extremes
v4: fix LIMIT OFFSET (and make a little bit cleaner)
v5: fix HAVING
v6: fix ORDER BY
v7: rebase against 20.7
v8: move out WithMergeableStateAfterAggregation
v9: add optimize_distributed_group_by_sharding_key into test names

Merge pull request #11715 from azat/dist-optimize_skip_unused_shards-fixes 
Control nesting level for shards skipping and disallow non-deterministic functions

041533eae2 Disable optimize_skip_unused_shards if sharding_key has non-deterministic func 
Example of such functions is rand()

And this patch disables only optimize_skip_unused_shards, i.e. INSERT
code path does not changed, so it will work as before.

c637d99e07 Volumes and storages refactoring: 
1. Moved Volume to separate file
  2. Created IVolume interface and implemented current behaviour in implementation of new interface — VolumeJBOD
  3. Replaced all old volume usages with new VolumeJBOD. Where it is unnecessary to have JBOD — left just IVolume.
  4. Removed old Volume completely
  5. Moved StoragePolicy to separated files
  6. Moved DiskSelector to separated files
  7. Removed DiskSpaceMonitor file

5d11118cc9 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.
