Bug Description
Too many period db actions in large scale clusters increase the load of database, especially un-necessary db update or query.
For example， over 1000 nodes, it will be 2 * 1000=2000 db update for compute_node table in 60s in _update_
Delete the first and second _update() in _init_compute_node can reduce two db update for one node in 60s, if resource usage not changed for this compute_node.
Then the funtion self._resource_
