Add required projects where necessary
Add required projects where necessary

Most of the jobs needs required-projects to be added, especially in
stable branches, where the lack of them causes gate failures.

Since the templates openstack-python3-jobs-neutron and
periodic-stable-jobs-neutron don't contain all the necessary projects
for bagpipe we need to add them one by one.
