fbb386dca5 Rewrite IN in query for remote shards to exclude values that does not belongs to shard
v2: fix optimize_skip_unused_shards_rewrite_in for sharding_key wrapped into function
v3: fix column name for optimize_skip_unused_shards_rewrite_in
v4: fix optimize_skip_unused_shards_rewrite_in with Null
v5:
- squash with Remove query argument for IStreamFactory::createForShard()
- use proper column after function execution (using sharding_key_column_name)
- update the test reference since (X) now is tuple(X)

5b3ab48861 More forward declaration for generic headers
The following headers are pretty generic, so use forward declaration as
much as possible:
- Context.h
- Settings.h
- ConnectionTimeouts.h
(Also this shows that some missing some includes -- this has been fixed)

And split ConnectionTimeouts.h into ConnectionTimeoutsContext.h (since
module part cannot be added for it, due to recursive build dependencies
that will be introduced)

Also remove Settings from the RemoteBlockInputStream/RemoteQueryExecutor
and just pass the context, since settings was passed only in speicifc
places, that can allow making a copy of Context (i.e. Copier).

Approx results (How much units will be recompiled after changing file X?):

- ConnectionTimeouts.h
  - mainline: 100

- Context.h:
  - mainline: ~800
  - patched:  415

- Settings.h:
  - mainline: 900-1K
  - patched:  440 (most of them because of the Context.h)

f25c1742b8 Pass through *_for_user settings via Distributed with cluster-secure
In cluster-secure case the user on shards (remote) is equal to the user
on the initiator, so those settings can be safely applied.
