[openstack-dev] [neutron][networking-ovn][tempest] devstack: gate-tempest-dsvm-networking-ovn failures in Openstack CI

With the recent commits it seems that the gate-tempest-dsvm-networking-ovn 
is succeeding more or less every time. The DBDeadlock issues still are 
seen on q-svc logs but are not frequent enough to cause ovsdb failures 
that were leading to the dsvm-networking failing before.

Once in a while a test fails for e.g. 
tempest.api.network.test_dhcp_ipv6.NetworksTestDHCPv6.test_dhcpv6_two_subnets 
that failed recently in Jenkins. But I am pretty sure it will succeed if 
the suite is re-run.

Should the gate-tempest-dsvm-networking-ovn become voting at this time, 
and re-run/re-check if it fails in the Jenkins check?
