5001b19613 Accept arbitrary numeric types for numbers() arguments (for scientific notation)
This is to make the syntax simpler, i.e. avoid explicit cast to UInt64
if you want to use scientific notation (i.e. 1e9 over 1 000 000 000).

v2: use plain evaluateConstantExpression() over
evaluateConstantExpressionOrIdentifierAsLiteral() since identifier will
not work anyway

b5ace27014 Add fsync support for Distributed engine.
Two new settings (by analogy with MergeTree family) has been added:

- `fsync_after_insert` - Do fsync for every inserted. Will decreases
  performance of inserts.

- `fsync_tmp_directory` - Do fsync for temporary directory (that is used
  for async INSERT only) after all part operations (writes, renames,
  etc.).

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)

99ee127620 Support SETTINGS clause for File engine
Accept the usual user settings related to file formats.

Most of the diff are the mechanistic code changes required to allow
providing the required FormatSettings to the format factory. The File
engine then extracts these settings from the `CREATE` query, and specifies
them when creating the format parser.
