Install Horizon from git repository in tox test

To test UI plugins, we should install recent Horizon
from master branch like CI infra does.

Also, this patch adds new testenv:py35dj20, due to
Horizon has plan to bump Django version to 2.0.

And new testenv:jstests for eslint and karma is added.

To run tox test easily before upload patchset,
adds py35dj20, jstests, docs and releasenotes to envlist.
