[oslo] Feature Freeze is this week

Apologies for not mentioning this in the meeting this week, but Oslo Feature Freeze is already this Friday.[0] After Friday, anything that is not a bug fix will need a feature freeze exception in order to merge. If you're wondering why Oslo freezes early, there's a doc[1] for that. If you have any questions not answered there, feel free to reply here or ping me on IRC. Thanks. -Ben 0: https://releases.openstack.org/ussuri/schedule.html 1: https://specs.openstack.org/openstack/oslo-specs/specs/policy/feature-freeze...
