Add missing packages

- `version` is used for getting the operator version and the operator SDK version in the logs.
- `k8suitl` is extracted from the operator-sdk to be able to fetch the namespace the operator is deployed to. This is used to deploy Connect in the same namespace if `MANAGE_CONNECT` is set to `true`. In the future, we may want to no rely on this, since this functionality is internal in the operator-sdk.
