Compute manager should remove dead resources
While most hypervisors return a single - and constant - value from
driver.get_available_nodes, baremetal does not. When a node is deleted
from the baremetal database, it is no longer returned from
driver.get_available_nodes. However, Nova's compute_node record is not
directly updated.
This patch allows Compute Manager to detect missing nodes within
update_available_resources. It then invokes resource_tracker to update
the dead node and remove it from compute.
This in turn allows the ServiceGroup API to properly update the
servicegroup when a baremetal node is no longer in service.
Fixes bug 1138184
