+ decreasing CPUs, per Kat/Matt

[Intra-broker partition balancing] has moved out of beta and is supported for production clusters. This dynamically balances partitions across cores within a Redpanda broker. You also can decrease the number of CPUs assigned to a broker. Existing partition replicas are reassigned to the remaining CPU cores when the broker restarts with fewer available cores.
