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. DB::Exception: No interserver IO endpoint
          named DataPartsExchange:/clickhouse/tables/default/a1/01/replicas/02.
          (NO_SUCH_INTERSERVER_IO_ENDPOINT)
