Updated OPA version, OPA config and default/example rego policies
This can be safely applied to M22 and M23 releases
- Updated OPA version to current - contains ignore cache headers feature, memory/cache fixes and security updates - on AWS
- OPA config to set max cache - on AWS
- Updated default legal policy - commonly used
- Updated test policy - not used during release but don't want it to be accidently used
