Subject: [PATCH] Use upper-constraints in tox installs

The tox targets do not currently use upper constaints, resulting in
stable branch test runs pulling down newer library versions than what
should be supported for those releases.

This adds upper-constaints for test environment setup.

Change-Id: I1ff164242901a891fb45da03b1595b2e9246a765
Closes-bug: #1596246
(cherry picked from commit c9e1a1aabc0ffb4b60b9327916ab9a65df98087a)
