Remove imports from __future__ module

[dorothykiz1]

The future module was introduced in Python 2.1 in order to have access to upcoming features/functions which will lead to incompatibilities with the current implementation and is extended with each version if needed.

Since we are trying to remove python 2 related dependencies. We will remove this particular import from all files for files that have it.
To be removed: from __future__ import (absolute_import, division, print_function, unicode_literals)
