Two cgroups are created prior running the scheduler tests:
- /cpuset/spdk
- /cpuset/all
/cpuset/spdk is the cgroup dedicated for the tests, i.e., the SPDK
processes executed along the way. The resources consist of the cpus
that are initially picked up by isolate_cores.sh.
/cpuset/all is the "dummy" cgroup that holds most of the remaining
processes that run on the target system - "most" since not every
process (especially kernel threads) can be migrated between cgroups.
This cgroup's resources include all the online cpus except those
selected for the /cpuset/spdk.
This should allow for lowering the noise on the target SPDK's cpus
and make sure that load on each cpu is generated exclusively by the
SPDK.
Fixes issue #1950

These functions are meant to help in isolating processes to make sure
SPDK is exclusively run on the dedicated cpus.

current test only include intel acpi-cpufreq and pstate. Add test
of cppc_cpufreq which works on most arm platforms.

Also, create a common dir which will hold symlinks to all existing
plugins used in the tests. Location of the actual lib is not changed
so the relation to the given test suite is clearly preserved.

This main goal of this "library" is to provide the following:
- Handling view of the cpu|numa topology as seen by the kernel
- Mapping cpufreq subsystem to cross-reference it with how
DPDK's librte_power governor behaves.
