A new Zuul job for trove-tempest-plugin itself

Recently there are new patches in this plugin, it's necessary all new
tests will be tested, however the current
python-troveclient-tempest-neutron-src job in fact does not run any
tests of trove-templest-plugin(only the default tempest api and scenario
tests are included). This patch add a new job only for this plugin
itself, we may also could just remove the
python-troveclient-tempest-neutron-src job later.
