There was some cases when some patches to the datetime code leads to
flaky tests, due to the tests itself had been runned using regular
timezone (TZ).
But if you will this tests with something "specific" (that is not
strictly defined around 1970 year), those tests will fail.
So to catch such issues in the PRs itself, let's randomize
session_timezone as well.

* 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.
