Hervé Beraud 3d476079a4 Stop to use the __future__ module.
The __future__ module [1] was used in this context to ensure compatibility
between python 2 and python 3.

We previously dropped the support of python 2.7 [2] and now we only support
python 3 so we don't need to continue to use this module and the imports
listed below.

Imports commonly used and their related PEPs:
- `division` is related to PEP 238 [3]
- `print_function` is related to PEP 3105 [4]
- `unicode_literals` is related to PEP 3112 [5]
- `with_statement` is related to PEP 343 [6]
- `absolute_import` is related to PEP 328 [7]

glance_store development environment setup is complete.
glance_store development uses virtualenv to track and manage Python
dependencies while in development and testing.
To activate the glance_store virtualenv for the extent of your current shell
session you can run:
$ source .venv/bin/activate
Or, if you prefer, you can run commands in the virtualenv on a case by case
basis by running:
$ tools/with_venv.sh <your command>
Also, make test will automatically use the virtualenv.
