Function validate_compute_node_memory_config 

fn validate_compute_node_memory_config(
    cn_total_memory_bytes: usize,
    reserved_memory_bytes: usize,
    storage_memory_bytes: usize,
) -> usize

Check whether the compute node has enough memory to perform computing tasks. Apart from storage, it is recommended to reserve at least MIN_COMPUTE_MEMORY_MB for computing and SYSTEM_RESERVED_MEMORY_PROPORTION of total memory for other system usage. If the requirement is not met, we will print out a warning and enforce the memory used for computing tasks as MIN_COMPUTE_MEMORY_MB.
