Internal Checklist

• [x] I am requesting a review from my own team as well as the owning team
• [x] I have a plan in place for the monitoring of the changes that I am making (this can include new monitors, logs to be aware of, etc...)

Changes

=======

• In policy decide, compile config only when context is config
• Also, remove the requirement of owner-id for compilation

Rationale

=========

The policy feature could be used non CircleCI-config related areas as well in the future. But, the compilation is relevant to circleci configs only.

Considerations

==============

It was understood that ownerid is not needed policy compilation, so that check is also removed.

Here are some helpful tips you can follow when submitting a pull request:

1. Fork the repository and create your branch from main.
2. Run make build in the repository root.
3. If you've fixed a bug or added code that should be tested, add tests!
4. Ensure the test suite passes (make test).
5. The --debug flag is often helpful for debugging HTTP client requests and responses.
6. Format your code with gofmt.
7. Make sure your code lints (make lint). Note: This requires Docker to run inside a local job.
