Clone tempest before installing the package
Rally and refstack require a tempest working dir. It now clones the offical repository before running setup.py develop. 14.0 is selected to conform with OpenStack upper-constraints.txt. Dockerfile downloads the official OpenStack upper-constraints.txt to remove the condition about tempest which forbids cloning it.
