236a0c4081 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]

b0e56ac646 Retire deprecations for constants, exceptions, attributes
Subprojects have had enough time to switch to neutron-lib for
the deprecated items from these modules.

99cfd671be debtcollector for globals
The deprecation shim created by Doug turns out to be rather useful.
It emits a warning when an global (attribute of a module) is
referenced but that global has been moved to another module.

This update makes the following changes to the shim:

 - Rename it to _MovedGlobals to better describe what it is a
   debtcollector for.

 - Use inspect to get the original reference and to check that
   _MovedGlobals is called from the last line of a module.

 - Save the old reference automatically in the instance to prevent it
   from getting garbage collected.

 - Beef up the _moved_global() method for moving/renaming individual
   globals, allowing it to move and rename or rename in place.

This tools list the constants and exceptions that have moved
to neutron-lib. Add it to pep8 to raise awareness of moved
globals.
