Start/stop servers when `listen_host`/`*_port` changes

Start/stop servers when listen_host/*_port changes
This allows starting and stopping separately each protocol server
without restarting ClickHouse.

This also allows adding or removing `listen_host` entries, which
start and stops servers for all enabled ports.

When stopping a server, the listening socket is immediately closed
(and available for another server).

Protocols with persistent connections try to wait for any currently
running query to finish before closing the connection, but idle
connection are closed quickly (depending on how often the protocol
is polled).

An extra ProfileEvent is added, `MainConfigLoads`, it is
incremented every time the configuration is reloaded. This helps
when trying to assess whether the new configuration was applied.

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.

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)
