Use error info during integration testing

[khieta]

Describe the improvement you'd like to request

Our integration testing framework supports providing a "custom implementation" of the Cedar validator and authorizer to allow testing new implementations. If a custom implementation is provided, then we ignore the "errors" field of the integration tests, which records which policies are expected to error during an authorization request.

We'll eventually want to update this to enforce that error behavior is consistent between different implementations of Cedar.

Note: We can’t do this until we update the implementations in cedar-spec to return authorization error info.

Closing this issue, since it was addressed during the last round of integration test revisions. I believe this particular issue was addressed in #707.
