optimize select query from cluster table function
...
Use local node as first priority to get Structure Of Remote Table.
we have many distributed queries( like select xx from cluster('xx',view (xxxx) ) on a clickhouse cluster. we found that the first node (shard_num=1) have 2 times of query number compared to other shards.
The reason is that the getStructureOfRemoteTableInShard func always take the first shard to execute "DESC TABLE xx" query.
The better way is to use local node as first priority which save the network rpc and reduce the pressure of first shard .

Pass through *_for_user settings via Distributed with cluster-secure
...
In cluster-secure case the user on shards (remote) is equal to the user
on the initiator, so those settings can be safely applied.
