There is a unique index on the compute_nodes.uuid column which means we can't have more than one compute_nodes record in the same DB with the same UUID even if one is soft deleted because the deleted column is not part of that unique index constraint. This is a problem with ironic nodes where the node is 1:1 with the compute node record, and when a node is undergoing maintenance the driver doesn't return it from get_available_nodes() so the ComputeManager.update_available_resource periodic task (soft) deletes the compute node record, but when the node is no longer under maintenance in ironic and the driver reports it, the ResourceTracker._init_compute_node code will fail to create the ComputeNode record again because of the duplicate uuid. This change handles the DBDuplicateEntry error in compute_node_create by finding the soft-deleted compute node with the same uuid and simply updating it to no longer be (soft) deleted.
