Title:
  Nova scheduler not updated immediately when a baremetal node is added

Status in OpenStack Bare Metal Provisioning Service (Ironic):
  New
Status in OpenStack Compute (Nova):
  Triaged

Bug description:
  In compute manager, the update_available_resource() periodic task is
  responsible for updating the scheduler's knowledge of baremetal nodes:

      @periodic_task.periodic_task
      def update_available_resource(self, context):
          ...
          nodenames = set(self.driver.get_available_nodes())
          for nodename in nodenames:
              rt = self._get_resource_tracker(nodename)
              rt.update_available_resource(context)

  update_available_resource() is also called at service startup

  This means that you have to wait up to 60 seconds for a node to become
  available
