Create a Software Qualification Testing for Release new versions

Currently we don't have any kind of Qualification Testing to confirm that a regression wasn't included in our code base.

A good starting point is the "ostest" (at apps/testing/ostest) and the SIM CI test, but these tools alone are not enough to detect regressions.

We need some test to exercise many NuttX features and drivers. The recent email in the mailing list about the Rotating Log not working as expected is an example of basic test that we are failing to execute.

Please share ideas how to cold create some automated tests to help to exercise more NuttX features and drivers as possible.
