UniversalOptions type used for redis package TODO(mredolatti): In order to avoid breaking the API, the struct now contains all original fields of go-redis' UniversalOptions struct, with our custom ones. Next time we bump toolkit's version, we should instead wrap or embed the original struct as well.
