c341b3b237 Add current database to table names in JOIN section for distributed queries 
This should fix JOIN w/o explicit database.

v2: rewrite only JOIN section, since there is old behavior that relies
on default_database for IN section, see [1]:
- 01487_distributed_in_not_default_db
- 01152_cross_replication

aee034a597 Use explicit template instantiation for SystemLog 
- Move some code into module part to avoid dependency from IStorage in SystemLog
- Remove extra headers from SystemLog.h
- Rewrite some code that was relying on headers that was included by SystemLog.h

v2: rebase
v3: squash move into module part with explicit template instantiation
    (to make each commit self compilable after rebase)

97851bde08 Fix Distributed over Distributed for WithMergeableStateAfterAggregation* stages 
In case if one Distributed has multiple shards, and underlying
Distributed has only one, there can be the case when the query will be
tried to process from Complete to WithMergeableStateAfterAggregation,
which is obviously wrong.

ff12f5102a Avoid running LIMIT BY/DISTINCT step on the initiator for optimize_distributed_group_by_sharding_key 
Before the following queries was running LimitBy/Distinct step on the
initator:

  select distinct sharding_key from dist order by k

While this can be omitted.

2fb95d9ee0 Rework SELECT from Distributed query stages optimization 
Before this patch it wasn't possible to optimize simple SELECT * FROM
dist ORDER BY (w/o GROUP BY and DISTINCT) to more optimal stage
(QueryProcessingStage::WithMergeableStateAfterAggregationAndLimit),
since that code was under
allow_nondeterministic_optimize_skip_unused_shards, rework it and make
it possible.

Also now distributed_push_down_limit is respected for
optimize_distributed_group_by_sharding_key.

Next step will be to enable distributed_push_down_limit by default.

v2: fix detection of aggregates
