Before it was initialized from disk only on startup, but if some INSERT
can create the object before, then, it will lead to the situation when
it will not be initialized.

Since #44922 it is not a directory monitor anymore.

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

Initializing queues for pending on-disk files for async INSERT cannot be
done after table had been attached and visible to user, since it
initializes the per-table counter, that is used during INSERT.
Now there is a window, when this counter is not initialized and it will
start from the beginning, and this could lead to CANNOT_LINK error:
Destination file /data/clickhouse/data/urls_v1/urls_in/shard6_replica1/13129817.bin is already exist and have different inode

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.
