Similar to the server_side_encryption_customer_key_base64 option for
configuring SSE-C with S3, add the following settings to configure
SSE-KMS on a per-endpoint/disk basis:
- server_side_encryption_kms_key_id
- server_side_encryption_kms_encryption_context
- server_side_encryption_kms_bucket_key_enabled
The S3 table engine supports specifying extra HTTP headers in S3
requests to certain endpoints, via the "headers" setting. This commit
adds the same setting to S3 disk config.
Reused external variable from src/Storages/System/StorageSystemTimeZones.generated.cpp
Required changes to CMakeLists of some standalone modules to link
properly
After #36425 there was a lot of confusions/problems with configuring pools - when the message was confusing, and settings need to be ajusted in several places.
See some examples in #44251, #43351, #47900, #46515.
The commit includes the following changes:
1) Introduced a unified mechanism for reading pool sizes from the configuration file(s). Previously, pool sizes were read from the Context.cpp with fallbacks to profiles, whereas main_config_reloader in Server.cpp read them directly without fallbacks.
2) Corrected the data type for background_merges_mutations_concurrency_ratio. It should be float instead of int.
3) Refactored the default values for settings. Previously, they were defined in multiple places throughout the codebase, but they are now defined in one place (or two, to be exact: Settings.h and ServerSettings.h).
4) Improved documentation, including the correct message in system.settings.
Additionally make the code more conform with #46550.
There are lots of thread pools and simple local-vs-global is not enough
already, it is good to know which one in particular uses threads.

Here the problem is that system.columns has cached value for number of
total table to iterate, and so it can skip something.
But anyway, this should be LOGICAL_ERROR, since ODBC bridge does two
queries:
- to system.tables and
- to system.columns
And if between this two queries the table will be removed, them there
will be no columns

We have an issue when using external dictionary. Occasionally library bridge called with extDict_libClone and fails with Unknown library method 'extDict_libClone'. And it looks like it is because of at some point `else if (method == "extDict_libNew")` was changed to if (lib_new) with no handling for extDict_libClone inside this new if else statement and reporing an error that extDict_libClone is an unknown method.
So there is a two-line fix to handle extDict_libClone properly.
Error logs that we have:

Introduce new `--connection` option, by default as a connection name
`--host` will be used.
And using --connection you also can specify --host and it will be
overwritten.

There are very frequent flakiness of `test_cluster_copier` test, here is
an example of copier failures on CI [1]:
AssertionError: Instance: s0_1_0 (172.16.29.9).

assert 85 == 0
But let's look what the error it is, apparently it is UNFINISHED:
SELECT

WHERE ((code % 256) = 85) AND (NOT remote)
SETTINGS system_events_show_zero_values = 1

└──────────────────────────────────┴──────┘
Let's verify:
$ grep -r UNFINISHED ./test_cluster_copier/_instances_0/s0_1_0/logs/copier/clickhouse-copier_*
./test_cluster_copier/_instances_0/s0_1_0/logs/copier/clickhouse-copier_20230206220846_368/log.log:2023.02.06 22:09:19.015251 [ 368 ] {} <Error> : virtual int DB::ClusterCopierApp::main(const std::vector<std::string> &): Code: 341. DB::Exception: Too many tries to process table cluster1.default.hits. Abort remaining execution. (UNFINISHED), Stack trace (when copying this message, always include the lines below):
And apparently that it is due to query error with fault injection:
2023.02.06 22:09:15.654724 [ 368 ] {} <Error> Application: An error occurred while processing partition 0: Code: 62. DB::Exception: Syntax error (Query): failed at position 168 ('Native'): Native.

(SYNTAX_ERROR), Stack trace (when copying this message, always include the lines below):
Example:

Syntax error: failed at position 32 ('Native'):
So fixing this should fix test_cluster_copier flakiness.

Sorry for the clickbaity title. This is about static method
ConnectionTimeouts::getHTTPTimeouts(). It was be declared in header
IO/ConnectionTimeouts.h, and defined in header
IO/ConnectionTimeoutsContext.h (!). This is weird and caused issues with
linking on s390x (##45520). There was an attempt to fix some
inconsistencies (#45848) but neither did @Algunenano nor me at first
really understand why the definition is in the header.
Turns out that ConnectionTimeoutsContext.h is only #include'd from
source files which are part of the normal server build BUT NOT part of
the keeper standalone build (which must be enabled via CMake
-DBUILD_STANDALONE_KEEPER=1). This dependency was not documented and as
a result, some misguided workarounds were introduced earlier, e.g.
0341c6c54b
The deeper cause was that getHTTPTimeouts() is passed a "Context". This
class is part of the "dbms" libary which is deliberately not linked by
the standalone build of clickhouse-keeper. The context is only used to
read the settings and the "Settings" class is part of the
clickhouse_common library which is linked by clickhouse-keeper already.
To resolve this mess, this PR
- creates source file IO/ConnectionTimeouts.cpp and moves all
ConnectionTimeouts definitions into it, including getHTTPTimeouts().
- breaks the wrong dependency by passing "Settings" instead of "Context"
into getHTTPTimeouts().
- resolves the previous hacks
This is somehow analog of .netrc [1].

The follow options can be overwritten on a per-hostname/connection
basis:
- hostname
- port
- secure
- user
- password
- database
- history_file
Also note, that you can have multiple settings for one hostname, can be
useful to distinguish readonly from non-readonly for example.
