Cope better with out of sync bm data.
The baremetal hypervisor tracks references to instances which are
deleted asynchronously from the commit to the nova bm. As such, its a
normal but rare condition for a bare metal node to refer to a deleted
(and even garbage collected) nova instance. We should treat such
instances are deleted rather than erroring on any call through
list_instances(), permitting starting new instances and listing
instances to work - fixing bug: 1096722.
Pathologically, the database may suffer permanent skew, which means we
need a way to fix it (and thats tracked as a separate bug).
