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.).

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)
