> The infra/OpenDev team continues to make good progress towards this transition and plans to perform the transition on April 19, 2019 as previously scheduled.  We will begin the transition at 15:00UTC and users should plan for intermittent Gerrit and git repo outages through the day. We expect most of those will be closer to 15:00UTC than 23:00UTC.

i guess networking-l2gw-tempest-plugin should go to the same namespace
with networking-l2gw.
