* 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

I saw the following in the logs for the failed test:
2023.05.16 07:12:12.894051 [ 262 ] {74575ac0-b296-4fdc-bc8e-3476a305e6ea} <Warning> ConnectionPoolWithFailover: Connection failed at try №1, reason: Timeout exceeded while reading from socket (socket (172.16.3.2:9000), receive timeout 2000 ms)
And I think that the culprit is the
test_distributed_replica_max_ignored_errors for which it is normal,
however not for others, and this should not affect other tests.
So fix this by calling SYSTEM RELOAD CONFIG, which should reset error
count.

woboq codebrowser uses clang tooling, which adds clang system includes
(in Linux::AddClangSystemIncludeArgs()), because none of (-nostdinc,
-nobuiltininc) is set.
And later it will complain with -Wpoison-system-directories for added by
itself includes in InitHeaderSearch::AddUnmappedPath(), because they are
starts from one of the following:
- /usr/include
- /usr/local/include
The interesting thing here is that it got broken only after upgrading to
llvm 16 (in #49678), and the reason for this is that clang 15 build has
system includes that does not trigger the warning -
"/usr/lib/clang/15.0.7/include", while clang 16 has
"/usr/include/clang/16.0.4/include"
So let's simply disable this warning, but only for woboq.
