+      Array of hashes describing the custom providers for the compute role.
+      Format:
+      name/uuid - Resource providers to target can be identified by either
+      UUID or name. In addition, the value $COMPUTE_NODE can be used in
+      the UUID field to identify all nodes managed by the service.
+      Exactly one of uuid or name is mandatory. If neither uuid or name
+      is provided, the special uuid $COMPUTE_NODE gets set in the template.
+
+      inventories - (Optional) Hash of custom provider inventories. 'total' is
+      a mandatory property. Any other optional properties not populated will
+      be given a default value by placement. If overriding a pre-existing
+      provider values will not be preserved from the existing inventory.
+
+      traits - (Optional) Array of additional traits.
