Update hacking to 0.10.0

Replace the whitelist of flake8 checks (select) with a blacklist
(ignore).  It makes possible to disable a single check, which was not
possible before. This new approach permits to enable new tests more
easily and see which checks are currently disabled.

Only new checks are disabled, this change doesn't run less checks than
before. Currently, many checks are disabled, but following changes will
fix these new warnings.

When the "select" option of flake8 is used in tox.ini, the "ignore"
option is ignored. It is not possible to use "select" and "ignore"
options at the same time. See the code in pep8 (flake8 is based on
pep8):

https://github.com/PyCQA/pep8/blob/d48eef071003952ed0f98445dc3dc6bc29618f9c/pep8.py#L1808

The purpose of flake8 is to enhance the coding style, but also to help
to detect common bugs. Blacklisting checks permits to detect new bugs
when upgrading the tools. For example, new checks were recently added to
help porting code to Python 3.

This change permits to use pbr 1.0 and newer which is required to
support Python 3. Previously, hacking 0.8.1 was used, but hacking 0.8 is
incompatible with pbr 1.0 and newer (hacking 0.8 requires pbr<1.0).

pbr 1.0 is required to use environment markers on requirements to
install dnspython on Python 2 and dnspython3 on Python 3.
