issue: https://github.com/milvus-io/milvus/issues/29846
Since checking if Milvus running inside the container is difficult,
which is decided by the system version and cgroup version, we try to get
the memory limit of the container each time instead of checking whether
inside the container first.

before this, Milvus use container/system's memory info to get the memory
usage, which could be inaccurate.
we allocates the memory by private anon mmap,
then `rss - shared` would be the accurate memory usage
