Add ara to the temp v3 project list
I want to make a simple test job for the log streaming and it's
important that it include ara since issues there can mess up the
zuul_stream plugin.
# but are ignored for configuration purposes.
projects:
- openstack-dev/devstack
+ - openstack/ara
- openstack/ceilometer
- openstack/ceilometermiddleware
- openstack/cinder
