- Add support for CSI spec v0.3.0 for both Cinder and Manilla
- Add 'cascade delete' support for Octavia load balancers to improve performance.
- Add improved load balancer naming.

### SIG-scheduling

SIG Scheduling development efforts have been primarily focused on improving performance and reliability of the scheduler.

- Scheduler doesn't run plugin's Filter method when its PreFilter method returned a Skip status.
  In other words, your PreFilter/Filter plugin can return a Skip status in PreFilter if the plugin does nothing in Filter for that Pod.
  Scheduler skips NodeAffinity Filter plugin when NodeAffinity Filter plugin has nothing to do with a Pod.
