Ghanshyam 56149024a0 Use stable constraint in run-tempest for stable branch testing
Stable branches till stable/rocky is using python
version <py3.6. Tempest test those branch in venv
but Tempest tox use the master upper-constraint[1]
which block installation due to dependencies
require >=py3.6. For exmaple, oslo.concurrency 4.0.0
is not compatible for <py3.6.

As we pin Tempest for EM stable brach, we should be
able to use stable constraint for Tempest installation
as well as while running during run-tempest playbook.

tox.ini is hard coded to use master constraint[1] which force
run-tempest to recreate the tox env and use the master constraint.

Devstack can set stable u-c to use via env var but this is
not enough as Tempest role run-tempest recreate the tox
env with master u-c.

Currently we are fixing run-tempest to use stable constraint
till stable/rocky which use distro having <py3.6.

Ideally, we can change compatible branch constraint in tox.ini
while doing release tag for Tempest. But that can be done
for future tags only.
