Note: We added this to the google_redis_instance resource directly, but got feedback that some users would have preferred it be added separately, to avoid having secrets in state in the general case. We could consider using that approach here, using a datasource instead.

I'm not sure why the ca certs would be secrets. As far as I know, they don't expose the private keys
