Since the dependent patch was merged in Neutron, we need to call
the register_common_config_options method explicitly to register common
options like oslo.log options.
This change updates the job template according to the tested runtimes
for Zed. This is required to remove Python 3.6/7 because these are no
longer supported.
Also, now unit tests are executed with current master code of Neutron,
instead of the latest release, so that we can run test with any
unreleased change in Neutron.
