[nova] Spec review sprint Tuesday June 04

Hi all. We would like to do a nova-specs review push next Tuesday, June 4th. If you own one or more specs, please try to polish them and address any outstanding downvotes before Tuesday; and on Tuesday, please try to be available in #openstack-nova (or paying close attention to gerrit) to discuss them if needed. If you are a nova reviewer, contributor, or stakeholder, please try to spend a good chunk of your upstream time on Tuesday reviewing open Train specs [1]. Thanks, efried [1] Approximately: https://review.opendev.org/#/q/project:openstack/nova-specs+status:open+path...
