Passing cpu_mask hints that match only single core were
usefull to prevent any accidents when doing round-robin
in case of 'static' scheduler.
In practice this is not required in case of 'static' scheduler,
the threads will be spread out over all reactors anyway.
This hinders other schedulers which try to respect the cpu_mask
hints, as they would not move the thread to any reactor.
Preventing bunching up less used threads on single reactor.
Drawback of this patch is that poll group names will not match
the cores they are on.

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.

Simplify the test to follow the scheduler period in order to check if
target thread is properly balanced among selected cpus.

Issues like https://github.com/spdk/spdk/issues/1784 showed that
governor may need some more time to properly adjust cpufreq's sysfs
knobs. In case we see that frequency setting hasn't changed after
given iteration, wait for 0.5s to make sure it finally settles.

- 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.
