New system table zookeeper connection (#45245) 
* Feature: Support new system table to show which zookeeper node be connected

Description:
============
Currently we have no place to check which zk node be connected otherwise using
lsof command. It not convenient

Solution:
=========
Implemented a new system table, system.zookeeper_host when CK Server has zk
this table will show the zk node dir which connected by current CK server

Noted: This table can support multi-zookeeper cluster scenario.

* fixed review comments

* added test case

* update test cases

* remove unused code

* fixed review comments and removed unused code

* updated test cases for print host, port and is_expired

* modify the code comments

* fixed CI Failed

* fixed code style check failure

* updated test cases by added Tags

* update test reference

* update test cases

* added system.zookeeper_connection doc

* Update docs/en/operations/system-tables/zookeeper_connection.md

* Update docs/en/operations/system-tables/zookeeper_connection.md

* Update docs/en/operations/system-tables/zookeeper_connection.md

2996b38606 Add ability to configure maximum load factor for the HASHED/SPARSE_HASHED layout 
As it turns out, HashMap/PackedHashMap works great even with max load
factor of 0.99. By "great" I mean it least it works faster then
google sparsehash, and not to mention it's friendliness to the memory
allocator (it has zero fragmentation since it works with a continuious
memory region, in comparison to the sparsehash that doing lots of
realloc, which jemalloc does not like, due to it's slabs).

Here is a table of different setups:

settings                         | load (sec) | read (sec) | read (million rows/s) | bytes_allocated | RSS
-                                | -          | -          | -                     | -               | -
HASHED upstream                  | -          | -          | -                     | -               | 35GiB
SPARSE_HASHED upstream           | -          | -          | -                     | -               | 26GiB
-                                | -          | -          | -                     | -               | -
sparse_hash_map glibc hashbench  | -          | -          | -                     | -               | 17.5GiB
sparse_hash_map packed allocator | 101.878    | 231.48     | 4.32                  | -               | 17.7GiB
PackedHashMap 0.5                | 15.514     | 42.35      | 23.61                 | 20GiB           | 22GiB
hashed 0.95                      | 34.903     | 115.615    | 8.65                  | 16GiB           | 18.7GiB
**PackedHashMap 0.95**           | **93.6**   | **19.883** | **10.68**             | **10GiB**       | **12.8GiB**
PackedHashMap 0.99               | 26.113     | 83.6       | 11.96                 | 10GiB           | 12.3GiB

As it shows, PackedHashMap with 0.95 max_load_factor, eats 2.6x less
memory then SPARSE_HASHED in upstream, and it also 2x faster for read!

Allow using Alias column type for KafkaEngine 
```
create table kafka
(
 a UInt32,
 a_str String Alias toString(a)
) engine = Kafka;

create table data
(
  a UInt32;
  a_str String
) engine = MergeTree
order by tuple();

create materialized view data_mv to data
(
  a UInt32,
  a_str String
) as
select a, a_str from kafka;
```
Alias type works as expected in comparison with MATERIALIZED/EPHEMERAL
or column with default expression.
