Added new tests for NUMA related behavior of scheduler
Created by: PeterPuhov-Linaro
LISA can be used to test scheduler behavior for task placement on hardware with complex NUMA topology. I already submitted Pull Request to devlib for NUMA introspection: https://github.com/ARM-software/devlib/pull/441
This Pull Request has a couple of very basic tests to ensure that tasks with relatively low utilization do not migrate to different cores. I am planning to add NUMA related tests in my next Pull Request after some NUMA related changes in rt-app.
