cgroups, i.e. control groups, are a linux kernel feature. this is not
available on FreeBSD, Win32 or MacOS. furthermore, we are reading the
information of it by accessing files exposed using a tmpfs filesystem
mounted at /sys/fs/cgroup, which is not available on other systems.
in this change, instead of guarding it using `#ifndef _WIN32`, it is now
guraded using `defined(__linux__)`.

Recently, nfs related code was moved out of volumes plugin[1]. So using the
name volume/nfs for the interface is not appropriate.

There already is a test to verify the mempool sharding works, in the sense that
it uses at least half of the variables available to count the number of
allocated objects and their total size. This new test verifies that, with
sharding, object counting is at least twice faster than without sharding. It
also collects cacheline contention data with the perf c2c tool. The manual
analysis of this data shows the optimization gain is indeed related to cacheline
contention.
