ci failing on cmd2 pip

[Michele Baldessari]

Even though we pinned cmd2 to 0.8.5 via https://review.openstack.org/#/c/570816/ in oooq. It seems
CI is still failing:
https://review.rdoproject.org/jenkins/job/gate-tripleo-ci-centos-7-ovb-3ctlr_1comp-featureset001-master/14979/console

Seems we need to either wait for the upstream fix to propagate everywhere:
https://github.com/python-cmd2/cmd2/issues/421

Or we prolly need to fix it in devstack-gate as well:
https://github.com/openstack-infra/devstack-gate/blob/master/devstack-vm-gate-wrap.sh#L480

    Add constraints to stable/newton

    cmd2 has dropped py2 support but the upper-constraints.txt will prevent
    the inclusion of the new version. We should use the stable constraints
    for testing.

    Avoid tox_install.sh for constraints support

    We do not need tox_install.sh, pip can handle constraints itself
    and install the project correctly. Thus update tox.ini and remove
    the now obsolete tools/tox_install.sh file.

    This follows https://review.openstack.org/#/c/508061 to remove
    tools/tox_install.sh.
