Subject: [PATCH] Support upper-constraints in tox.ini

Update tox.ini to use upper constraints.
Since python-freezerclient is itself listed in upper-constraints.txt
we need to add some workaround. tox-install.sh was copied from
python-neutronclient [1].

[1] http://git.openstack.org/cgit/openstack/python-neutronclient/tree/tools/tox_install.sh

Change-Id: I9fb37f1bc103e487e139087125058ef63a26efd1
Closes-Bug: #1644612
