Make some Tempest gates voting

This commit makes following gates voting:
* tempest-kuryr-kubernetes-lbaasv2
* tempest-kuryr-kubernetes-lbaasv2-daemon
* tempest-kuryr-kubernetes-octavia

I was supposed to provide stability graphs from graphite.openstack.org,
but it looks like data from Zuul v3 is not put in there.
