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

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

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).
