Instead of using the default linux memory check (mem), Check_MK is now using the container specific memory check.
The main reason is that the memory information in the container is not available through /proc/meminfo as usual. The memory data is available through the kernels cgroup interface which is available in the containers context below /sys/fs/cgroup/memory/memory.stat
The features of both checks are exactly the same.
