We added check_drive to the account/container servers to unify how all the storage wsgi servers treat device dirs/mounts. Thus pushes that unification down into the consistency engine. Drive-by: * use FakeLogger less * clean up some repeititon in probe utility for device re-"mounting" Related-Change-Id: I3362a6ebff423016bb367b4b6b322bb41ae08764 Change-Id: I941ffbc568ebfa5964d49964dc20c382a5e2ec2a
