Review Comment:
@vincbeck
the purpose of this implementation is to give users an option _not failing_
the dag.
setting `fail_on_file_not_exist` to `False` means the user is trying to skip
the task and get informed about FileNotFound case, while _not failing_ the dag.
just like @ferruzzi said, the code does look much cleaner but users won't be
able to know if the task succeeded because the file existed or just skipped
task even if the file did not exist.
in my opinion **its better to have logging** so that users can be informed
about the file existence.
