1358a2db92 Fix WithMergeableStateAfterAggregationAndLimit with LIMIT BY and LIMIT OFFSET 
In case of LIMIT BY, pre LIMIT cannot be applied (that is done on the
shard before), and hence shard applies regular LIMIT, but it goes with
applying OFFSET, and also the initiator will do apply OFFSET too.

18e8f0eb5e Add ability to push down LIMIT for distributed queries 
This way the remote nodes will not need to send all the rows, so this
will decrease network io and also this will make queries w/
optimize_aggregation_in_order=1/LIMIT X and w/o ORDER BY faster since it
initiator will not need to read all the rows, only first X (but note
that for this you need to your data to be sharded correctly or you may
get inaccurate results).

Note, that having lots of processing stages will increase the complexity
of interpreter (it is already not that clean and simple right now).

Although using separate QueryProcessingStage looks pretty natural.

Another option is to make WithMergeableStateAfterAggregation always, but
in this case you will not be able to disable only this optimization,
i.e. if there will be some issue with it.

v2: fix OFFSET
v3: convert 01814_distributed_push_down_limit test to .sh and add retries
v4: add test with OFFSET
v5: add new query stage into the bash completion
v6/tests: use LIMIT O,L syntax over LIMIT L OFFSET O since it is broken in ANTLR parser

Projections 
TODO (suggested by Nikolai)

1. Build query plan fro current query (inside storage::read) up to WithMergableState
2. Check, that plan is simple enough: Aggregating - Expression - Filter - ReadFromStorage (or simplier)
3. Check, that filter is the same as filter in projection, and also expression calculates the same aggregation keys as in projection
4. Return WithMergableState if projection applies

3 will be easier to do with ActionsDAG, cause it sees all functions, and dependencies are direct (but it is possible with ExpressionActions also)

Also need to figure out how prewhere works for projections, and
row_filter_policies.

8703b7863d Fix distributed_group_by_no_merge=2 with GROUP BY 
Before this patch the following query:

  SELECT assumeNotNull(argMax(dummy, 1))
  FROM remote('127.1', system.one)
  SETTINGS distributed_group_by_no_merge = 2

Leads to:

  Code: 10. DB::Exception: Received from localhost:9000. DB::Exception: Not found column argMax(dummy, 1) in block: while executing 'INPUT : 0 -> argMax(dummy, 1) UInt8 : 0'.

Since it tries to execute function one more time, but shards will not
send this column when the query processed with
distributed_group_by_no_merge=2 (i.e. up to
WithMergeableStateAfterAggregation).

v0: no exception
v2: execut window functions
v3: throw exception, since executing window function in this case will
lead to messy output
