Add zookeeper name in endpoint id (#49780) * Add zookeeper name in endpoint id When we migrate a replicated table from one zookeeper cluster to another (the reason why we migration is that zookeeper's load is too high), we will create a new table with the same zpath, but it will fail and the old table will be in trouble. Here is some infomation: 1.old table: CREATE TABLE a1 (`id` UInt64) ENGINE = ReplicatedMergeTree('/clickhouse/tables/default/a1/{shard}', '{replica}') ORDER BY (id); 2.new table: CREATE TABLE a2 (`id` UInt64) ENGINE = ReplicatedMergeTree('aux1:/clickhouse/tables/default/a1/{shard}', '{replica}') ORDER BY (id); 3.error info: <Error> executeQuery: Code: 220. DB::Exception: Duplicate interserver IO endpoint: DataPartsExchange:/clickhouse/tables/default/a1/01/replicas/02. (DUPLICATE_INTERSERVER_IO_ENDPOINT) <Error> InterserverIOHTTPHandler: Code: 221.
