ab8f13b885 Add --stage option for clickhouse-client
It is sometimes useful to process queries not up to the Complete stage
but intermediate some (i.e. for Distributed queries debugging and
similar).

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)

4043be3121 Add new query processing stage WithMergeableStateAfterAggregation
Process query until the stage where the aggregate functions were
calculated and finalized.

It will be used for optimize_distributed_group_by_sharding_key.

v2: fix aliases
v3: Fix protocol ABI breakage due to WithMergeableStateAfterAggregation
    Conditions >= for QueryProcessingStage::Enum has been verified, and they
    are ok (in InterpreterSelectQuery).
