test: New test file for validating kernel status during sync ops

First test in this file checks whether 'aa' is ever spotted during
a "recover" operation (it should not be).  More tests should follow
in this file to look for oddities in status output - especially as
it relates to the sync_ratio, dev_health, and sync_action fields.
