Provisioner asks the backend, not memory, whether a consumer is still there

An optional holds() on the adapter is asked for every applied consumer
every minute; false applies it again. A backend that forgets what it was
given while the provisioner runs (hq issue 120) is healed within a
minute instead of failing its consumers in silence. Unable to ask is not
treated as loss. Adapters without holds() behave as before.
