Installation and deployment

• Counts the CPU cores of all nodes (instead of only compute nodes) in the cluster against the cpu_core_limit specified in the license key. https://github.com/risingwavelabs/risingwave/pull/23390
• Changes cpu_core_limit in the license key to rwu_limit to limit both CPU cores and total cluster memory. https://github.com/risingwavelabs/risingwave/pull/23403
