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.

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)
