📄 Description

This pull request can be performance improvement for inference using CPUs in a container like Kubernetes Pods.
Kubernetes and Docker have CPU and memory limitation features using cgroups. But Ollama cannot be fetch CPU and memory information from it. So Ollama start too many threads in a limited environment and encount performance decrement.

This pull request changes for this problem to read /sys/fs/cgroup/cpu.max and /sys/fs/cgroup/memory.(max|current) when these files exist.
