v.23.12Backward Incompatible Changes

MergeTree Setting clean_deleted_rows Deprecated; CLEANUP in OPTIMIZE Disabled by Default

The MergeTree setting clean_deleted_rows is deprecated, it has no effect anymore. The CLEANUP keyword for the OPTIMIZE is not allowed by default (it can be unlocked with the allow_experimental_replacing_merge_with_cleanup setting). #58267 (Alexander Tokmakov). This fixes #57930. This closes #54988. This closes #54570. This closes #50346. This closes #47579. The feature has to be removed because it is not good. We have to remove it as quickly as possible, because there is no other option. #57932 (Alexey Milovidov).
