Can not recover a clusetr in warning status by senlin-dashboard

[lidong]

when i shut down a instance related to a node in a cluster ,i found that the status of the node became error，the status of the cluster became warning after checking cluster. I wanted to recover the cluster ,but i failed by senlin-dashboard.

And i found that below：
in this file：.../senlin-dashboard/blob/master/senlin_dashboard/cluster/clusters/tables.py
line 91: return datum.status == "ERROR" in func allowed(self, request, datum).
and i changed it : return datum.status == "ERROR" or datum.status == "WARNING"
and i recovered the cluster ,the instance which i shut down was active ,running again.And the node、the cluster related were active again.
