fffeeeba06 Force WithMergeableStateAfterAggregation via distributed_group_by_no_merge (convert to UInt64) 
Possible values:
- 1 - Do not merge aggregation states from different servers for distributed query processing - in case it is for certain that there are different keys on different shards.
- 2 - same as 1 but also apply ORDER BY and LIMIT stages

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

4043be3121 Add new query processing stage WithMergeableStateAfterAggregation 
Process query until the stage where the aggregate functions were
calculated and finalized.

It will be used for optimize_distributed_group_by_sharding_key.

v2: fix aliases
v3: Fix protocol ABI breakage due to WithMergeableStateAfterAggregation
    Conditions >= for QueryProcessingStage::Enum has been verified, and they
    are ok (in InterpreterSelectQuery).
