feat: OnCreateCatalog (#8)

* feat: OnCreateCatalog

- Update onCreateCatalog to support credential rotation. Service authentication type creds will be rotated since we will have the credentials for the base service account without sufficient permissions.
- `onCreateCatalog` will also do a dry run validation to validate the credentials.
- The secrets and last rotated time will be returned
