Discuss a plan to address the gate failures

• Current failure rate: https://goo.gl/L1WODG
  • Multinode was broken by https://review.openstack.org/#/c/233711/ and fixed by https://review.openstack.org/#/c/245697/
  • All the jobs except multinode-dvr appear to have stabalized at similar failure rates. regXboi to consult with armax, mestery and dougwig about returning these jobs to voting next week.
• Debug the gate in the current failure state (Identify owners who can own this)
• https://bugs.launchpad.net/neutron/+bug/1515360 - Tempest "SSHTimeout" failures
  • https://review.openstack.org/#/c/247748/ (add debugging code to l3-agent)
