The Python 2.7 Support has been dropped since Ussuri.
So remove hacking rules for compatibility between python 2 and 3.

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]

The repo is Python 3 now, so update hacking to version 3.0 which
supports Python 3.
Fix problems found.
Remove hacking and friends from lower-constraints, they are not needed
for installation.

Fixed a TypeError when running with python3, and also added
a 'benchmark3' target to run it on python3 explicitly.

Move the public API out of oslo.rootwrap to oslo_rootwrap. Retain
the ability to import from the old namespace package for backwards
compatibility for this release cycle.

Benchmark shows performance penalty rootwrap introduces compared to one of
plain sudo.
To run benchmark, issue: tox -e benchmark
