The builtin platform.linux_distribution[1] is deprecated and will be
removed in 3.8 and the recommended replacement is distro.
This also raises a "deprecated method" error in pylint.
This patch moves us over to the future by following the recommendation
in the python docs and switching to use the "distro" module.

We want to default to running all tox environments under python 3, so
set the basepython value in each environment.
We do not want to specify a minor version number, because we do not
want to have to update the file every time we upgrade python.
We do not want to set the override once in testenv, because that
breaks the more specific versions used in default environments like
py35 and py36.
This patch also updates pylint to 1.5.6 which is compatible with
python3.
In updating pylint we have some issues to correct, this patch addresses
those issues so the Octavia code passes pylint 1.5.6.
