Joe McDonnell 82bd087fb1 IMPALA-11973: Add absolute_import, division to all eligible Python files
This takes steps to make Python 2 behave like Python 3 as
a way to flush out issues with running on Python 3. Specifically,
it handles two main differences:
 1. Python 3 requires absolute imports within packages. This
    can be emulated via "from __future__ import absolute_import"
 2. Python 3 changed division to "true" division that doesn't
    round to an integer. This can be emulated via
    "from __future__ import division"

This changes all Python files to add imports for absolute_import
and division. For completeness, this also includes print_function in the
import.

I scrutinized each old-division location and converted some locations
to use the integer division '//' operator if it needed an integer
result (e.g. for indices, counts of records, etc). Some code was also using
relative imports and needed to be adjusted to handle absolute_import.
This fixes all Pylint warnings about no-absolute-import and old-division,
and these warnings are now banned.

Testing:
 - Ran core tests
