If you push data via Buffer engine then all your queries will be done
from one user, however this is not always desired behavior, since this
will not allow to limit queries with max_concurrent_queries_for_user and
similar.

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)
Add distributed_ddl.pool_size to control maximum parallel to handle
distributed DDL.
Also:
- convert Exception constructors to fmt-like
- use sleepFor* over std::this_thread::sleep_for()
This PR adds a server level config for overriding the default max number
of threads in global thread pool that is currently allowed (10,000).
This might be useful in scenarios where there are a large number of
distributed queries that are executing concurrently and where the
default number of max threads might not be necessarily be sufficient.
