17eaddc3ab Prevent hedged connections overlaps 
Some replicas may be in the establishing state, this means that hedged
connection is waiting for TablesStatusResponse, and if the connection
will not be canceled, then next user of the connection will get
TablesStatusResponse, while this is not the expected package, and you
will see:

    DB::Exception: Received from localhost:9000. DB::Exception: Received from ch-1:9000. DB::Exception: Unknown packet 9 from server ch-2:9000: While executing Remote. Stack trace:

Fix this by disconnecting connection to such replicas, note that this
should be fine in general, since they are "slow" anyway (you may wish
configure hedged requests settings to increase timeouts and similar).

921518db0a CLICKHOUSE-606: query deduplication based on parts' UUID 
* add the query data deduplication excluding duplicated parts in MergeTree family engines.

query deduplication is based on parts' UUID which should be enabled first with merge_tree setting
assign_part_uuids=1

allow_experimental_query_deduplication setting is to enable part deduplication, default ot false.

data part UUID is a mechanism of giving a data part a unique identifier.
Having UUID and deduplication mechanism provides a potential of moving parts
between shards preserving data consistency on a read path:
duplicated UUIDs will cause root executor to retry query against on of the replica explicitly
asking to exclude encountered duplicated fingerprints during a distributed query execution.

NOTE: this implementation don't provide any knobs to lock part and hence its UUID. Any mutations/merge will
update part's UUID.

* add _part_uuid virtual column, allowing to use UUIDs in predicates.

109dbe5df4 Check the stream before sending while hanlding async INSERTs into Distributed 
It is possible to get corruption (even though it is very unlikely, and
initially it wasn't corruption) just before the data block goes in the
file on disk, and in case of batching, it will break the packets, since
it will write the packet type but will not write any data after.

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)

0159c74f21 Secure inter-cluster query execution (with initial_user as current query user) [v3] 
Add inter-server cluster secret, it is used for Distributed queries
inside cluster, you can configure in the configuration file:

  <remote_servers>
      <logs>
          <shard>
              <secret>foobar</secret> <!-- empty -- works as before -->
              ...
          </shard>
      </logs>
  </remote_servers>

And this will allow clickhouse to make sure that the query was not
faked, and was issued from the node that knows the secret. And since
trust appeared it can use initial_user for query execution, this will
apply correct *_for_user (since with inter-server secret enabled, the
query will be executed from the same user on the shards as on initator,
unlike "default" user w/o it).

v2: Change user to the initial_user for Distributed queries if secret match
v3: Add Protocol::Cluster package
v4: Drop Protocol::Cluster and use plain Protocol::Hello + user marker
v5: Do not use user from Hello for cluster-secure (superfluous)
