Should this just be the new default or do you see value in setting custom intervals?

This PR adds a new
--receive.compaction-delay-intervalflag to stagger head compaction across tenants deterministically. When set, tenant N gets a delay of N*interval (mod block duration), ensuring compactions are evenly distributed over time. This is useful for deployments with many tenants where the current random delay may still cause compaction clustering and CPU spikes. The default value of 0 preserves the existing random delay behavior.rolled out in a dev cluster and CPU spikes during compaction is greatly reduced
