        Description

        In the VM's error log, the container information was dumpped as:
        ---------------------------------
        container (cgroup) information:
        container_type: cgroupv1
        cpu_cpuset_cpus: 0-11
        cpu_memory_nodes: 0
        active_processor_count: 12
        cpu_quota: -1
        cpu_period: 100000
        cpu_shares: -1
        memory_limit_in_bytes: -1
        memory_and_swap_limit_in_bytes: -2
        memory_soft_limit_in_bytes: -1
        memory_usage_in_bytes: 11690164224
        memory_max_usage_in_bytes: 1806413824
        ---------------------------------

        Items such as "memory_limit_in_bytes" and "memory_and_swap_limit_in_bytes" are difficult to understand.

        It might be more human-readable if we could dump it like this:
        ---------------------------------
        container (cgroup) information:
        container_type: cgroupv1
        cpu_cpuset_cpus: 0-11
        cpu_memory_nodes: 0
        active_processor_count: 12
        cpu_quota: no quota
        cpu_period: 100000
        cpu_shares: no share
        memory_limit_in_bytes: unlimited
        memory_and_swap_limit_in_bytes: failed
        memory_soft_limit_in_bytes: unlimited
        memory_usage_in_bytes: 11690164224
        memory_max_usage_in_bytes: 1806413824
        ---------------------------------
