Depend on tempest in test-requirements.txt

This replaces the requirements.stub dependency approach for
heat_integrationtests with a single dependency on tempest in
test-requirements.txt.

tempest provides all the required dependencies for the current
heat_integrationtests, and this helps the transition of being able to
run tests both with the current runner and as a tempest plugin.
