- lots of static_cast
- add safe_cast
- types adjustments
- config
- IStorage::read/watch
- ...
- some TODO's (to convert types in future)
P.S. That was quite a journey...
v2: fixes after rebase
v3: fix conflicts after #42308 merged

This makes the target location consistent with other auto-generated
files like config_formats.h, config_core.h, and config_functions.h and
simplifies the build of clickhouse_common.
The original motivation for this commit was that shared_ptr_helper used
std::shared_ptr<>() which does two heap allocations instead of
make_shared<>() which does a single allocation. Turned out that
1. the affected code (--> Storages/) is not on a hot path (rendering the
performance argument moot ...)
2. yet copying Storage objects is potentially dangerous and was
previously allowed.
Hence, this change
- removes shared_ptr_helper and as a result all inherited create() methods,
- instead, Storage objects are now created using make_shared<>() by the
caller (for that to work, many constructors had to be made public), and
- all Storage classes were marked as noncopyable using boost::noncopyable.
In sum, we are (likely) not making things faster but the code becomes
cleaner and harder to misuse.
This allows starting and stopping separately each protocol server
without restarting ClickHouse.
This also allows adding or removing `listen_host` entries, which
start and stops servers for all enabled ports.
When stopping a server, the listening socket is immediately closed
(and available for another server).
Protocols with persistent connections try to wait for any currently
running query to finish before closing the connection, but idle
connection are closed quickly (depending on how often the protocol
is polled).
An extra ProfileEvent is added, `MainConfigLoads`, it is
incremented every time the configuration is reloaded. This helps
when trying to assess whether the new configuration was applied.
Which logs all the info about LogIn, LogOut and LogIn Failure events.
Additional info that is logged:
- User name
- event type (LogIn, LogOut, LoginFailure)
- Event date\time\time with microseconds
- authentication type (same as for IDENTIFIED BY of CREATE USER statement)
- array of active settings profiles upon login
- array of active roles upon login
- array of changed settings with corresponding values
- client address and port
- interface (TCP\HTTP\MySQL\PostgreSQL, etc.)
- client info (name, version info)
- optional LoginFailure reason text message.
Added some tests to verify that events are properly saved with all necessary info via following interfaces:
- TCP
- HTTP
- MySQL
Known limitations
- Not tested against named HTTP sessions, PostgreSQL and gRPC, hence those are not guaranteed to work 100% properly.
* client query kind is not set for mysql and postgresql
* Update MySQLHandler.cpp
* Update PostgreSQLHandler.cpp
