Add user_domain_name in the user object

user_domain_name is exposed by keystoneclient, adding
this information for horizon as well.

Configurable token hashing algorithm

The user's authentication token was hashed using the MD5 algorithm.
The MD5 algorithm shouldn't be used because of the potential for
hash collisions. Some security standards mandate a SHA2 algorithm
or better must be used.

With this change the algorithm to use for hashing tokens can be
configured by setting the OPENSTACK_TOKEN_HASH_ALGORITHM
configuration option to a hash algorithm supported by Python's
hashlib library[1]. For example, a deployer could set the option to
'sha256' to meet a SHA2 security standard.

The algorithm chosen must match the hash algorithm that the
identity server is configured to use (Keystone and the auth_token
middleware can be configured to use any hash algorithm supported by
hashlib).

This is for security hardening.

Closes-Bug: #1174499
Added url_path_replace and has_in_url_path methods

utils.py, views.py and backend.py were using .replace('v3', 'v2.0') and
.replace('v2.0', 'v3') methods on url strings.
This is BAD because if you have v3 in your url's domain it brakes it.

A new url_path_replace method now only performs the replaces in the url path
and leaves the domain unchanged.

Some checks where performed to test if a substring was in the url path but the
tests where performed on the whole url and could return a false positive if the
substring exists in the domain name or in the query string.
The new has_in_url_path method checks only if the substring is in the path of
the url.

Fix Django 1.7 compat

In Debian, we are going to release Jessie with Django 1.7,
which has just been released. Therefore, compatibility is
important for us.

This patch, which the Debian package already carries, fixes
2 small compatibility issues with Django 1.7. It is safe to
use openstack_auth with these patches and a lower version of
Django, which makes it safe to apply this patch.

Adding django kwargs to login and logout views

The django.contrib.auth.views login and logout views take usefull parameters
which where dropped by the openstack_auth.views methods.

Added a TOKEN_TIMEOUT_MARGIN which allows to check token expiration minus a
time margin in seconds. This is usefull if you know a process will take a
certain time, you want to have your token still valid all this time (e.g. the
time it can take to render a view).

This patch is required for https://review.openstack.org/88220
