Creating on daemon startup time make sure that the directory is
recreated/adjusted if it was mangaled by an evil admin. But that's not a
good excuse. I don't think there was a good one.

it should move to somewhere standard, and the "rhev" trademark should be
dropped. It could happen on ovirt-4.0 when we break backward
compatibility. But that's easier said than done.

How about opening 2 infra bugs for 4.0 for these?
