* 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.

* Fix incompatible with a new setting
* add a test, fix other issues
* Update 02442_auxiliary_zookeeper_endpoint_id.sql
* Update 02735_system_zookeeper_connection.reference
* Update 02735_system_zookeeper_connection.sql
* Update run.sh
* Remove the 'no-fasttest' tag
* Update 02442_auxiliary_zookeeper_endpoint_id.sql
