Is there any best practices around how to manage provider credentials in Pulumi? We recently needed to update some provider credentials (datadog) where the old credentials were revoked. Our stack explicitly created a provider instead of using the default provider, and the refresh operation failed because I believe it was using the old credentials that were saved in the state file. I think we can fix this by running up to update the provider credentials, but ideally we could roll away from revoked creds without also applying changes.
