      Description

      Currently some OSContainer functions use direct CGroup V1 implementation details. This should be made more agnostic so as to accommodate for a future CGroup V2-based implementation (See JDK-8230305).

      The proposal is dispatch to cgroup version agnostic implementations for the following functions:

        static const char * container_type();
        static jlong memory_limit_in_bytes();
        static jlong memory_and_swap_limit_in_bytes();
        static jlong memory_soft_limit_in_bytes();
        static jlong memory_usage_in_bytes();
        static jlong memory_max_usage_in_bytes();
        static char * cpu_cpuset_cpus();
        static char * cpu_cpuset_memory_nodes();
        static int cpu_quota();
        static int cpu_period();
        static int cpu_shares();

      This would allow for support for cgroup v2 without actually changing OSContainer code for those functions.
