a55798626a Revert "Merge pull request #44922 from azat/dist/async-INSERT-metrics"
There are the following problems with this patch:
- Looses files on exception
- Existing current_batch.txt on startup leads to ENOENT error and hung
  of distributed sends without ATTACH/DETACH
- Race between creating the queue for sending at table startup and
  INSERT, if it had been created from INSERT, then it will not be
  initialized from disk

They were addressed in #45491, but it makes code more cmoplex and plus
since, likely, the release is comming, it is better to revert the
change.

This reverts commit 94604f71b7, reversing
changes made to 80f6a45376.

4e76629aaf Fixes for -Wshorten-64-to-32
- 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

Don't let storages inherit from boost::noncopyable
... IStorage has deleted copy ctor / assignment already

Remove inherited create() method + disallow copying
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.

Improvements for parallel_distributed_insert_select (and related) (#34728)

* Remove Cluster::getHashOfAddresses()

* Forbid parallel_distributed_insert_select for remote()/cluster() with different addresses

Before it uses empty cluster name (getClusterName()) which is not
correct, compare all addresses instead.

* Fix max_distributed_depth check

max_distributed_depth=1 must mean not more then one distributed query,
not two, since max_distributed_depth=0 means no limit, and
distribute_depth is 0 for the first query.

empty.

2fb95d9ee0 Rework SELECT from Distributed query stages optimization
Before this patch it wasn't possible to optimize simple SELECT * FROM
dist ORDER BY (w/o GROUP BY and DISTINCT) to more optimal stage
(QueryProcessingStage::WithMergeableStateAfterAggregationAndLimit),
since that code was under
allow_nondeterministic_optimize_skip_unused_shards, rework it and make
it possible.

Also now distributed_push_down_limit is respected for
optimize_distributed_group_by_sharding_key.

Next step will be to enable distributed_push_down_limit by default.

a616ae8861 Improve startup time of Distributed engine.
- create directory monitors in parallel (this also includes rmdir in
  case of directory is empty, since even if the directory is empty it
  may take some time to remove it, due to waiting for journal or if the
  directory is large, i.e. it had lots of files before, since remember
  ext4 does not truncate the directory size on each unlink [1])
- initialize increment in parallel too (since it does readdir())
