[cinder] driver maintainers: 3rd party CI checkpoint reminder

Hello Cinder driver maintainers, Around the time of the Feature Freeze (10 September), the Cinder team will be looking at the Third Party CIs to assess compliance [0]. Out of compliance drivers will be marked as 'unsupported' in the Victoria release. We can avoid a lot of unpleasantness if you take this opportunity to review the current situation of your driver's CI [1] and, if necessary, take appropriate steps to get it back into compliance before 10 September. cheers, brian [0] https://docs.openstack.org/cinder/latest/drivers-all-about.html#driver-compl...
