Overview

New feature/design proposals always welcome!

User tooling for all Policy APIs.

Repurpose Cyclonus code into a Policy Assistant with these features:

1. Summarize policy interactions.
2. Analysis engine, simulating theoretical policy behavior.
3. Run conformance tests, which are quick to code by just specifying NetPols/(B)ANPs.

Builds off of #62, and replaces #69, breaking it into smaller issues.
