The best practice in Python is not to use mutable object (i.e. list,
dictionary, or instances of most classes) as value of default
argument (see https://goo.gl/Kwhg0T). A hacking rule to enforce this
practice is added as well.
The patch was inspired by CR https://review.openstack.org/#/c/198465/
and took most of its code from it as well. That's why original
copyrights are kept.

We have one more import with #noqa: django.conf.urls.include that is also
commonly used in urls.py module and could be included to the list of
import exceptions. This change has also revealed one unused import.

We have two imports with #noqa: django.conf.urls.patterns and
django.conf.urls.url however using them is a standard way of creating
any urls.py module. So there are over 150 imports in Horizon code
where #noqa could be replaced with two lines in list of import_exceptions.

Since there is a couple of new import exceptions in tox.ini,
we should add corresponding lines to HACKING.rst list.

Django changed the name to force_unicode and it's only available in
python2 as an alias of force_text. The new name is available since
Django 1.4.2

We have a lot of import with #noqa that is there to ignore h302,
because it's traditional to import and use a name directly, instead
of a whole module. This hides other errors and gives people the
impression that it's actually fine to import non-modules, you just
have to slap #noqa on those lines.
I went through the code and identified about a dozen names that are
most commonly imported this way. I remove the #noqa tag from them,
and added them to the list in import_exceptions.
I also removed a few unused imports that were revealed in the process.

Make HACKING.rst have the same format as in other OpenStack repos. When
working across multiple projects its nicer to have files have the same
formatting to reduce confusion.

The current links in the HACKING file are broken. This references the
correct location for contributors to view.

Add HACKING.rst but instead of copying the file around point to the new
cannonical location for it
https://github.com/openstack-dev/hacking/blob/master/HACKING.rst
Also expand out the flake8 H series ignores, so they can be enabled one
by one.
