* 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.
