Bump hacking to 1.1.0

Ignore W504 and F405 by configurations.
Reasons of disabling them are explained as comments in tox.ini.
They are already ignored in the horizon repository and
AFAICT it is not easy to avoid them in horizon plugins as well.

Fixes the following new error:
* E123 closing bracket does not match indentation of opening bracket's line
