When we select CPUs for the scheduler tests we pick up all siblings
from given core. On some nodes in the CI these threads may have IDs
in ranges that simply overflow during the shift operation ( > 62).
To avoid this, use a list instead of a mask. Also, deny all threads
with IDs > 127 as DPDK doesn't support them anyway.

The configuration is generated based on existing host's NUMA
topology (as seen via sysfs) instead of a total number of cpus as
it was done before. New logic attempts to load balance VMs and
their cpus based on nvme drives' NUMA location. If there is no
enough cpus left under the target node, all remaining nodes are
checked. For the sake of the performance, cpus are not mixed
between different numa nodes.
Disk map is created by mapping VMs to existing nvme drives
based on their NUMA location. Extra VMs are assigned in bus
order of the nvme drives.
SPDK cpus are split by matching the VM-to-nvme NUMA ratio.
Static list can be defined as well to override this behavior.

During tests, the main portion of the app's time is spent in user
mode when polling is in effect. Currently, the idleness of given cpu
is determined in comparision to all the possible states the cpu can
be in. This makes it easier for third party processes to impact the
idleness of the cpu (as it may be lowered via different kinds of
loads).
For instance, if target cpu suddenly sees spike in a system
load (even up to 100%) it should not be relevant for the test where
it's known that the app's polling utilized mainly user mode prior
switching the scheduler.
With that in mind, if the general idle check fails, lookup the
raw samples matching the user mode and if the load is relatively
low (<= 15%) consider this as a pass.

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.
