Dynamic Audit Backend policy design proposal is open for review and comments

One of the key milestones for the Dynamic Audit Backend feature introduced with k8s1.13 to transit to beta is a complete policy design.

The work on this progressed and it already shapes up. We aim at finalizing it soon and moving to implementation. On this stage we would like to reach out to the community for a preliminary validation. Please, feel free to review and provide feedback until next Friday(20-09-2019). Next sig auth meeting is a good opportunity to discuss it too.

Thanks!
