> As described by the parent task -
> Cleaner can be divided into separate entities like -
> *1) Handler* - This entity fetches the data from the metastore DB from
> relevant tables and converts it into a request entity called CleaningRequest.
> It would also do SQL operations post cleanup (postprocess). Every type of
> cleaning request is provided by a separate handler.
> *2) Filesystem remover* - This entity fetches the cleaning requests from
> various handlers and deletes them according to the cleaning request.
