* Since all the sahara tempest plugin code is moved to sahara-tests.
In RDO, openstack-sahara-tests package provides python-sahara-tests-tempest
which contains sahara tempest plugin. So we need to rename the package
from python-sahara-tests to python-sahara-tests-tempest.
* Fixed python-horizon-tests-tempest package name typo in rspec
