Accept the usual user settings related to file formats.
Most of the diff are the mechanistic code changes required to allow
providing the required FormatSettings to the format factory. The File
engine then extracts these settings from the `CREATE` query, and specifies
them when creating the format parser.
Contains error codes with number of times they have been triggered.
Columns:
- `name` ([String](../../sql-reference/data-types/string.md)) — name of the error (`errorCodeToName`).
- `code` ([Int32](../../sql-reference/data-types/int-uint.md)) — code number of the error.
- `value` ([UInt64](../../sql-reference/data-types/int-uint.md)) - number of times this error has been happened.
**Example**
``` sql

Current WAL format doesn't seem to be extendable without breaking
reverse compatibility.
This PR proposes to introduces a metadata section
for each action in the WAL to which optional fields can be added.
Adding new fields is trivial and doesn't have to break backwards
compatibility if these are not critical for correctness.
Metadata contains the minimum version of the reader allowed
to interpret it.
Removing fields is not supported.
Materialized view drop the inner table (if any) drop the drop() method,
and this will lead to essure recursive drop() from the drop worker
thread, which will hang:

Fix this by dropping the inner table just before scheduling job the the
drop worker thread.
Wrap them into StorageKafkaInterceptors to allow access to private
fields and add logging inside interceptors if something fails.
This is also preparation for ThreadStatus interceptor.
