Docs on using CUE and Rego to craft policies in policy-controller

[amdawson]

There are a couple of policy examples in the policy-controller docs that use cue policies, but I can't find any documentation that specifically address CUE and Rego support and how it works.

• Here's how to craft a CUE policy, here is the spec/language reference
• Here's how Rego policies work, here is the reference on how they need to be written (including custom error messages)

@amdawson I'm interested to take this up! Can you please provide me with some resources to get started? Or if you have anything specific regarding this, feel free to share! 😄
