 1. Create a new Kubernetes secret, with default values (default, no override config required)

 2. Use an existing Kubernetes secret, by configuring .Values.redisCache.connection.existingSecret

 3. Do not create or use Kubernetes secrets, just pass the default values directly as environment variables into the needed pods, by configuring .Values.sourcegraph.disableKubernetesSecrets = true
