Look at the results of each half of the query separately:
redis_memory_max_bytes{k8s_cluster_name="$cluster",
namespace="$namespace", pod="$pod_name"}
redis_instance_info{role=~"master|slave"}
You then need to find some set of labels which mean that N entries on the
left-hand side always match exactly 1 entry on the right-hand side.
