Testing neutron-lib periodically with unit test jobs from Neutron stadium
projects can help prevent breakages detected at the time of a neutron-lib
release and it will speed development and maturity of the library.
This patch introduces the configuration necessary for running unit
tests against the master version of neutron-lib. The support is limited
to py34, as that would suffice to ensure coverage.
